India arrests fourth suspect in Mumbai blasts

MUMBAI - Indian police have arrested a fourth man on suspicion of involvement in the Mumbai serial blasts that killed more than 180 people this month.

Tanvir Ansari, a doctor of traditional Indian medicine, was picked up by the crime branch of Mumbai police late on Sunday, police inspector Sunil Deshmukh said.

Ansari, a resident of Mumbai, was due to be produced in a city court later on Monday.

"We have arrested him on suspicion, for further interrogation. He has undergone training in Pakistan - that is the information we have," Deshmukh said.

Three men, all Indian Muslims, were arrested last week for their alleged role in the rush-hour blasts which ripped through first class carriages of Mumbai's commuter trains and platforms.

Investigators say Pakistan-based Islamist militant group Lashkar-e-Taiba and Pakistani military spy agency Inter-Services Intelligence were the prime suspects in the case.

Islamabad has rejected the charges as unsubstantiated and offered to help New Delhi in the investigations.
