LAHORE - Police security was stepped up around the University of Engineering and Technology (UET) in Lahore on Wednesday after the administration received a threatening letter sent by the militant group, Islamic State (IS).

Police have also launched a security sweep in the adjacent localities to hunt down suspected militants, police sources said. Reportedly, according to the letter, the militant group is planning suicide strikes or gun and bomb attacks to target the UET campus.

A spokesperson for the university, Dr Tanvir Qasim, confirmed the media reports stating that they had been received a threatening note via posted mail from an unidentified source. However, he did not share the contents of the letter with the media persons.

Lahore DIG (Operations) Dr Haider Ashraf said that police deployment was increased around the university while armed patrolling was intensified to check the movement of suspected persons. Police are also searching vehicles and suspected persons at the checkpoints set up around the university.

Speaking on the condition of anonymity, a police officer however, said that the letter could be a hoax. “It could be a hoax to spread panic in the town but we cannot ignore this threat. We are investigating the incident keeping in view various aspects of the happening,” he added. Police officials said that a search operation was launched in the UET hostels and around the campus premises late Wednesday.

In October, a similar threat letter was handed over to the guards of Kinnard College Lahore that later turned out to be a hoax.

Lahore police had also launched a manhunt to unearth the suspected elements behind an ISIS campaign after pamphlets, posters, and stickers of the banned outfit were seen on display on the boundary walls and roadside poles in different parts of the provincial metropolis.
