Mumbai, July 31 (IANS) US national Keith Haywood was summoned to the Anti-Terrorist Squad (ATS) headquarters Thursday and interrogated for over two hours in connection with the terror email sent by the ‘Indian Mujahideen’ from his email ID just before the serial bombings in Ahmedabad on Saturday. Haywood was present at the ATS headquarters with his lawyer.

The police found that the email was sent through Haywood’s email ID, which he claimed had been hacked by some unknown persons. The bombings killed at least 50 people and left over 200 injured.

Though Haywood has been questioned several times, he has not been formally arrested nor has his passport been seized. He has been ordered not to leave the country without clearance from the investigators, (ATS) chief Hemant Karkare said Thursday.

The police have also recovered certain spare components of his computer from his house. The components were purchased from Lamington Road in south Mumbai, a hub for new and used electronic goods.

Karkare said all the people who entered Gunina Apartments, where Haywood lives as a tenant, last Saturday would be treated as “suspects” in the investigations. The details of the visitors to the building are available in the entry logbook maintained by the building authorities.

A team of the National Security Guards (NSG) arrived here in connection with the investigations to unravel the terror networks operating in and around Mumbai, Karkare said.

In a related development, West Bengal Inspector General of Police Rajeev Kumar also visited the Mumbai police and ATS top brass Thursday evening in connection with the terror probe. Two days ago, a Gujarat police team had also visited the city in this regard.

Karkare declined to elaborate on this issue.

Following an advisory from the central government, Maharashtra has increased security for Shiv Sena chief Bal Thackeray.

He lives with son Uddhav and other family members at ‘Matoshri’ bungalow in Bandra east. The Sena chief is among the most heavily protected personalities in the state.

Meanwhile, Navi Mumbai police teams have launched intensive efforts to trace out over a thousand vehicles reported stolen from the area in the past year or so.

They will also attempt to find out which group or groups have stolen these vehicles, whether the motive was robbery for financial benefits or otherwise. The case files of all stolen vehicles will not be closed till the vehicles are traced, the police said.

Since the past five days, the police in Mumbai and Thane districts have either detained or questioned over a 100 suspects. No arrests have been made so far.
