"We have foiled a terrorists' plan and arrested two women and a man from Farid Kot Colony near the Kot Lakhpat Jail," a senior Lahore officer said.
The officials have seized a rocket launcher, uniforms of the security agencies, shoes, guns, bows and arrows, mobile phones and SIMs from their possession.
Deputy Inspector General Police Haider Ashraf confirmed the arrests of the three terrorists during a raid at a house in Farid Kot Colony. The suspects were taken away to an undisclosed location for interrogation.
According to the sources, the terrorists were planning to attack the Kot Lakhpat Jail and free the militants.
At least 50 militants including five terrorists who have been handed down death sentence by military courts are languishing in the Kot Lakhpat Jail.

Lahore High Court yesterday lifted the stay on their death sentences, as the government continued with the executions of convicted militants after the Peshawar school massacre that killed 150 people, mostly children.
"As their death warrants have been issued they may be executed any time," Kot Lakhpat Jail superintendent Asad Warriach said.
Prime Minister Nawaz Sharif's government has ended a six- year moratorium on executions after the Peshawar attack.
So far six death-row terrorists have been executed after the Peshawar attack.
