Ranchi: A crude bomb was hurled near Jharkhand Urban Development Minister Bachcha Singh's residence, while another was recovered from the spot intact in the wee hours on May 23, police said.

The bomb that exploded, however, did not cause any damage, they said.

They said while one bomb exploded, the other was found intact at the spot.

A first information report (FIR) has been lodged against unknown persons and the police were on the track to find out the miscreants.

This is the second time an explosion has occurred in front of Singh's residence.

During last year's domicile protests, unknown persons had lobbed a crude bomb near the official residence of the Minister.
