Police have arrested four more suspects in connection with July's train bombings in Mumbai that killed nearly 200 people and wounded more than 800 others.
Authorities identified the men as Mohammed Shafi, Shaikh Mohammed, Mohammed Majid and Abdul Vahiuddin. Police arrested three of the suspects in Mumbai and the fourth in the eastern city of Kolkata.
This raises the total number of arrests in the case to more than 15 people.
Indian officials say they suspect the Pakistan-based Lashkar-e-Toiba militant group was behind the attacks.
The group, which is fighting Indian rule in Kashmir, has denied involvement.
The explosions on packed commuter trains in Mumbai prompted police raids on the city's Muslim ghettos and the questioning of hundreds of people across the country.
