A contingent of 186 Elite Force commandos of Punjab police have arrived in the capital city to enhance security measures following two terrorism incidents within six weeks, the police said.
Another contingent of 40 personnel of the force will arrive in Islamabad soon, they added.
The personnel were demanded by the capital police for joint patrolling.
Apart from assigning them patrol duties at sensitive areas, separate teams will be deployed at different spots of the city, along with the Rangers and police, to react immediately and reach the trouble spot within a short time.
A security alert was issued on April 3, stating that the Tehrik-i-Taliban Pakistan (TTP) had planned to carry out terrorist attacks in three cities Islamabad, Rawalpindi and Wah Cantonment by using the name of a proxy outfit, according to police sources.
