Guwahati, Oct 1 (IANS): Assam Director General of Police Khagen Sarma on Thursday said anti-talk groups from the ULFA and NSCN(K) have entered the state to conduct subversive activities and added that both these outfits were behind Wednesday's attack on a police station.

Police were on the alert to foil attempts by these outfits to carry out their evil designs, Sarma told media persons on the sidelines of an Assam Police Day celebrations function at Kahilipara.

"The United Liberation Front of Asom (ULFA) and Nationalist Socialist Council of Nagaland (Khaplang) cadres wanted to attack in a big way but quick retaliation by an alert police force made the militants flee," the DGP said.

Militants attacked the Kakapathar police station in Tinsukia district around 8 p.m. on Wednesday with a Rocket Propelled Gun and automatic weapons. However, no one was injured in the incident.

"We have seen ULFA and NSCN(K) cadres come together in the recent past," Sarma said referring to the formation of United Liberation Front of Western South East Asia by the ULFA, NSCN(K) and some other north-eastern militant outfits.

Meanwhile, the DGP said the 67th Assam Police Day was being celebrated on Thursday with the aim of bringing police closer to the common people.

As part of the celebrations, the official function was inaugurated at the 4th Assam Police Battalion headquarters at Kahilipara on Thursday morning, with at least 48 cultural troupes representing different tribes and communities of Assam taking out rallies in and around the city.

Cultural functions would be held at Nehru stadium on Thursday evening, where people from all walks of life have been invited to witness performances by cultural troupes from different districts of the state.
