The Rajasthan police has arrested a man having alleged links with a Hindu militant outfit in connection with the 2007 Ajmer Dargah bomb blast, which killed three people and injured over 30 others.
The accused, Devendra Gupta, is expected to be produced before a local court on Friday, police sources said.
Gupta, a resident of Bihari Ganj in Ajmer, was arrested by the Rajasthan Anti-Terrorism Squad on Wednesday night when he had gone to meet his ailing mother, the sources said.
He is allegedly linked with Hindu outfit Abhinav Bharat Sangathan and is suspected to be involved in the blast inside the Dargah of Khawaja Moinuddin Chishty at Ajmer in October 2007, they said.
Officials are also probing Gupta's alleged link with Sadhvi Pragya Singh Thakur, a key suspect in the Malegaon blast case.
They said Gupta was staying in Jharkhand and had come to Ajmer on Wednesday.
A SIM card recovered from the blast site had helped the police trace him, they added.
