Four suspected cow smugglers have been arrested after police and members of a cow protection group intercepted a mini-truck here, police said on Friday.

Following a tip-off that some cow smugglers would pass near Sector 3 area yesterday, a police team set up a barricade there. Members of a local outfit, Shyam Bir Gaurakshak Samiti, were also present with the policemen.

"Policemen spotted a mini-truck carrying cows approaching from Ballabhgarh. The vehicle broke through the barricade even as its occupants opened fire on the policemen and the activists at the spot," police claimed.

But police succeeded in overpowering the occupants of the vehicle, identified as Salid from Haryana, Narendra of Madhya Pradesh and Raju and Bunty from Uttar Pradesh, and placed them under arrest.

A country-made pistol was also recovered from them and a case has been registered in this regard, they said.
