Police are investigating whether David Coleman Headley, arrested by the FBI for allegedly conspiring to carry out terror attacks in India, had any role in the Mumbai terror attacks, a senior crime branch official said.

"We are probing if Headley was involved in various terror activities here including the 26/11 terror strikes. He had an office in AC market building in Tardeo in south Mumbai. Crime branch team has earlier visited the building," Joint Police Commissioner Rakesh Maria said.

"Headley had visited Mumbai on several occasions and we have all details as to where he stayed and for how long," Maria, who supervised the 26/11 terror attacks probe, said.

According to sources, Headley's office used to provide visa and travel facilities.
