Bihar police on Thursday recovered a rocket launcher from the house of a former independent legislator Surendra Sharma, a criminal-turned-politician in Saran district.

Shocked by the recovery of a rocket launcher from Sharma house, Governor Buta Singh ordered Director General of Police Ashish Ranjan Sinha to investigate how Sharma came to possess the sophisticated combat weapon, used by the Indian Army.

Sharma is currently lodged in Chapra jail in connection with criminal cases.

A joint team of Special Task Force along with district police raided Sharma's house on Tuesday following a tip off that four abducted persons were kept at his house and recovered a rocket launcher, an AK 47 and huge arms and ammunition.

Sinha said that Sharma would be taken into police remand in a day or two for interrogation.
