A second suspect in the 2007 Ajmer Dargah blast case, allegedly linked with some Hind outfits, has been arrested by Rajasthan ATS from Madhya Pradesh. Chandrashekhar, who was arrested on Friday from Madhya Pradesh, was today produced before an Ajmer court which remanded him in 11-day police custody. He is suspected to be a key member of the terror module involved in the blast in which three persons were killed and is believed to have links with Hindu outfits. The sources said, Chandrashekhar is the second person to be arrested in connection with the case this week. On Wednesday, Devendra Gupta was arrested by Rajasthan Police in connection with the blast. Gupta is allegedly linked with Hindu outfit Abhinav Bharat Sangathan and suspected to be involved in the blast inside the Dargah of Khawaja Moinuddin Chishti. Officials are also probing Gupta's alleged links with Sadhvi Pragya Singh Thakur, a key accused in the Malegaon blast case. Both the accused will be produced again before the court on May 12.<br/><br/>
