Hi, yes a police officer can do so ,if they have an apprehension that a person may commit cognizable offence 

Hi

It has become a habit of police to harass innocent citizens by filing false cases U/S 109 Cr.p.c under the pretext that the accused was found moving in a suspicious manner concealing his presence with a view to commit a cognizable offence.  

Also 109 Cr.P.C is a tool adopted by police to tag the accused as history sheeter and harass the person and as such courts are generally very strict (in favour of accused and against police) when such cases are brought before them. 

However, even in case of unlawful arrest by police u/s109 Cr.P.C  police should produce the arrested person before the  Executive magistrate and the magistrate is duty bound to release the person immediately without sending him for remand,  if the person  executes a bond , with or without sureties for his good behaviour for such period not exceeding one year. 

The person arrested u/s 109   Cr.p.c should get the case quashed u/s 482 cr.p.c at High Court 

Hope this information is useful. 

Yes the police can arrest a person if he is found wondering in suspicious circumstances. There is nothing illegality in it.

Yes the police can arrest if such section is charged against innocent person then in that case the person can move to high court to quash such case and further can also seek bail.

When an Executive Magistrate receives information that there is within his local jurisdiction a person taking precautions to conceal his presence and that there is reason to believe that he is doing so with a view to committing a cognizable offence, the Magistrate may, in the manner hereinafter provided, require such person to show cause why he should not be ordered to execute a bond, with or without sureties, for his good behaviour for such period, not exceeding one year, as the Magistrate thinks fit.

2)police officer incharge of a police station may as a preventive measure arrestwithout warrant any person belonging to one or more of the categories of persons specified in Section 109 or Section 110 e. persons taking precautions to conceal their presence with a view of committing a cognizable offence

A police officer incharge of a police station may as a preventive measure arrest without warrant any person belonging to one or more of the categories of persons specified in Section 109 or Section 110  e. persons taking precautions to conceal their presence with a view of committing a cognizable offence, habitual robbers, housebreakers, thieves, etc. and persons habitually indulging in the commission of certain social and economic offences. 

Security for good behavior  from suspected persons:

When an Executive Magistrate receives information that there is within his local jurisdiction a person taking precautions to conceal his presence and that there is reason to believe that he is doing so with a view to committing a cognizable offence, the Magistrate may, in the manner hereinafter provided, require such person to show cause why he should not be ordered to execute a bond, with or without sureties, for his good behavior for such period, not exceeding one year, as the Magistrate thinks fit.

Police has no role to play in this.

A police officer incharge of a police station may as a preventive measure arrest without warrant any person belonging to one or more of the categories of persons specified in Section 109 or Section 110  e. persons taking precautions to conceal their presence with a view of committing a cognizable offence, habitual robbers, housebreakers, thieves, etc. and persons habitually indulging in the commission of certain social and economic offences.

1. Section 109 CrPC reads as "When[ an Executive Magistrate] 1 receives information that there is within his local jurisdiction a person taking precaution to conceal his presence and that there is reason to believe that he is doing so with a view to committing a cognizable offence, the Magistrate may in the manner hereinafter provided, require such person to show cause why he should not be ordered to execute a bond, with or without sureties, for his good behaviour for such. period, not exceeding one year, as the Magistrate thinks fit.".

2. Unless police arrests the person and produces him before magistrate the latter cannot exercise the power conferred on him by Sec.109, hence the answer to your question is in affirmative.

Not arrest but only execution of bond of good behaviour.

1. Police has ample power as per law to take into custody anyone on whom they may have any suspect.
2. Though it is also true that police officials take disadvantage  of this power vested in them by law of our country.
3. They can, but subject to the condition that the suspect will have to be produced before the Magistrate within 24 hours.
4. And then based on the information so given to him by police, will help him to decided as to whether a bond should be signed by you for not conducting any act for which you have been suspended to, and that bond will be in force at least one year or less but not beyond that.
