The head of a Hindu monastery has been arrested over suspected links with a bombing that killed six people and injured scores of others in western India in September, police said on Thursday.

Several other people with links to a right-wing Hindu outfit, including an army official, have already been arrested in connection with an attack near a mosque in the town of Malegaon in western India.

Police arrested the Hindu holy man, Sudhakar Dwivedi, in the northern state of Uttar Pradesh on Wednesday.

"He will be produced in the court today," police inspector general A.K Jain said.

No one claimed responsibility for the attack, which occurred in an area where relations between Hindus and Muslims have been strained in recent years.

Indian authorities have generally blamed Muslim militants for carrying out bomb attacks that have taken place regularly across India in recent months.

Some of the serial bombings were claimed by a group that calls itself the Indian Mujahideen.

Police are now probing right-wing Hindu groups on suspicion of involvement in some of the attacks.
