Gurdaspur, May 15 (PTI): Pathankot terror attack martyr Kulwant Singh's younger brother and his wife were allegedly thrashed by a travel agent and his accomplices over a monetary dispute, the police said today.

Hardip Singh and his wife, Kulwinder Kaur, were beaten up outside a shop in an area falling under Bhaini Mian Khan Police Station on May 13 and a video of the incident went viral on social media.

The dispute arose after Hardip gave Rs 9 lakh to the travel agent, Gurnam Singh, for sending him abroad, Gurdaspur Sub Inspector Vijay Kumar said.

After Gurnam failed to send him abroad, the family demanded that the money be returned. The agent gave them Rs 5 lakh and promised to return the balance amount as well, the police said.

When he failed to honour its promise, Hardip and his wife decided to lodge a police complaint.

On May 13, Hardip and his wife were on their way to a police station to lodge a complaint when they stopped at a shop to recharge a mobile phone.

There Gurnam's family members appeared and they allegedly started thrashing Hardip and Kulwinder.

A case has been registered against 11 persons, including Gurnam, under relevant sections of the IPC, the police said.

However, the family of travel agent was absconding, the police said.

Hawaldar Kulwant Singh was among the seven security personnel who lost their lives when four terrorists sneaked in from across the border and attacked the Pathankot air base on the intervening night of January 1 and 2 last year.

Kulwant was a resident of the Chak Sharif village in Gurdaspur.
