3 more arrested in Mumbai blasts probe

The three men were arrested in different areas of Nagpur in Maharashtra state, whose capital is Mumbai.

They were identified as Shakeel Wasi, 32, Shakir Ahmed Naseer, 27, and Mohammed Rehan Khan also aged 32, the police spokesman said.

The men belong to the Students Islamic Movement of India (SIMI), which is banned under India's anti-terrorism laws, he added.

SIMI advocates the "liberation of India" through its conversion into an Islamic land, according to the South Asia Terrorism Portal website, which tracks separatist trends.

The trio had been under surveillance since June when police foiled an attack by Islamic militants on the headquarters of the Rashtriya Swayamsewak Sangh, a right-wing Hindu group.

Police now have 14 suspects in custody in connection with the rush-hour train bombings, which also injured nearly 900 people.
