Two undertrials have escaped from a prison here in Anakapalli district after attacking the jail head warden, an official said on Saturday. 
"Two remand prisoners, Ramu (27) and Kumar (30), escaped from Chodavaram sub-jail around 4 pm on Friday after hitting the head warden with a hammer," Anakapalli Superintendent of Police Tuhin Sinha told PTI. Kumar, a panchayat secretary, who was on remand since April, hit the head warden with a hammer while returning the jail's kitchen keys after completing his cooking duties, he 
said.
During the ensuing melee between head warden V Veera Raju (45) and Kumar, Ramu rushed towards another room where guards were sleeping to lock it from outside to prevent them from helping the injured and bleeding warden, said Sinha.
Later, the duo managed to steal the main door's keys from the warden to flee, all of which occurred in two to three minutes and was captured on CCTV, said the SP. Following this jail break, Sinha said, a case of attempt to murder and escape from lawful custody was booked against Ramu and Kumar.
