Shillong:  The army chief of Garo Hill-based Garo Hill National Liberation Army (GNLA) militants of Meghalaya on Sunday gave a slip to the security forces when they raided a camp at a jungle in East Garo Hills district, the police said.

Acting on a tip-off that GNLA militants are camping in a steep jungle about two km south of Bawegre village in Williamnagar PS, Meghalaya's Special Weapons and Tactics (SWAT) commandos and CRPF's CoBRA stormed the camp at around 7 am, they said.

However, while approaching the camp, located in a dense steep slope, GNLA fired at the approaching security forces, the police said.

While there was no casualty from both sides, the militants escaped leaving behind arms, ammunition and other documents, the police said.

The police seized 66 high intensity bombs, a SBML gun and a mobile phone from the camp.

According to the police, the army chief of GNLA Sohan D Shira, a self-styled "C-in-C", was present in the camp and they believed that Shira is well guarded with not less than 10-15 heavily armed men around him.

The GNLA has been categorised as a terror organisation by the Centre in January this year.
