Indian police have reportedly arrested a suspect in the 2008 terrorist attacks on Mumbai.

The Press Trust of India says police have detained Sayed Zabiuddin, an alleged member of Lashkar-e-Taiba, the militant group India blames for the attacks.

The news organization says police tracked Zabiuddin for three years, arresting him last week when he arrived in India from a Gulf state.

The report says Zabiuddin was based in Pakistan at the time of the attack on Mumbai and issued instructions by telephone to the 10 Pakistanis who conducted the assault on luxury hotels, a Jewish center, and a busy train station in India's financial capital in November 2008, killing 166 people.

PTI describes Zabiuddin as a 30-year-old Indian, originally from Maharashtra state.

The news agency says Indian security agencies had interrogated detained terrorists about Zabiuddin and learned he operated out of “terror camps” in Karachi and Pakistan-controlled Kashmir.

The United States has offered a $10 million reward for information leading to the conviction of Hafiz Saeed, the founder of Lashkar-e-Taiba who lives openly in Pakistan and is accused of masterminding the Mumbai attacks.
