Police have booked a father-son duo for allegedly assaulting an 18-year-old youth of Sector 20.

The victim, Ratul Birla, in his complaint, told the police that he is a first-year student of BCA at SD College, Sector 32, Chandigarh.

His father works in FCI, Orissa, and his mother is a government teacher in Punjab.

He said on Friday, accused Saksham, who stays in the same locality, around 7 pm, called him asking to meet in the parking of a private hospital in Sector 20.

Upon reaching there, he saw Saksham standing there with 15 boys who were armed with sticks. Saksham asked him to stay away from his female friend and assaulted him. Saksham’s friend also filmed the attack on his mobile phone.

Ratul said he somehow ran away and called his father, Mohit. When he ran towards the society gate, he saw Mohit standing there. But instead of helping him, Mohit assaulted him, Ratul alleged. The accused fled after issuing threats.
