Under Railway Section 143Act.

My brother used to book IRCTC tickets from Agent ID, also used personal ID for tickets bookings for family and relatives & stopped doing this practice of booking tickets from personal ID since December 2019. On 3rd March 2020, Railway Police came to brother shop, checked all details, found nothing wrong. Brother also told them that he stopped booking tickets from personal ID since December 2019. They satisfied and went away. On next day around 12 PM afternoon, they came in 6-7 RPF officials. They came and take my brother as if he was a terrorist or rapist accused. They did not call anyone neither Gram Pradhan neither near Police man on the spot. They broke down some articles, take Computer and printers without any witnesses or panchnamas. So my question is in Railway Act 1989, what is the process on the following: 1) Does they have power to caught someone on tickets issued in 2018-19 under Railway Act 143. 2) Does they have power to arrest someone for tickets bookings case as if he were terrorist or rapist accused without in presence of Gram Pradhan or Police officer there. 3) Does they have to seize Computer, Printers and mobiles without Panchnamas and eyewitness. Kindly reply
