Police appear to have captured one of the suspected gunmen in the attack on a police academy in Pakistan's east.
An Associated Press photographer saw police take away a single suspect at the academy in Lahore.
Television footage also showed police and other security forces surrounding the bearded man and kicking him in a field outside the compound.
Security forces are engaged in a pitched battle with gunmen holed up inside the academy walls. Officials say the attack early Monday has killed at least 11 police officers and wounded more than 90 people.
