A local court in Surendrangar district on Sunday remanded three cops in three-day police custody in connection with the last year's Thanagadh police firing incident in which three dalits were killed.

The state CID, probing the firing incident, on Saturday arrested sub-inspector KP Jadeja, constables Nathubha Jhala and Yogesh Gadhvi, who were on the run after three dalits were allegedly killed in a police firing in Thanagadh during a clash in September last.

"A local court in Muli town in Surendranagar district on Sunday remanded the trio in three-day police remand in this connection", said CID (Crime) DySP SP Trivedi.

A Dalit community boy was killed on the spot and three others seriously injured when police opened fire to disperse the violent mob that clashed with members of other community at Thanagadh in Surendranagar district on September 22, 2012, after holding of a fair.

Two of the three boys later succumbed to gunshot injuries.

The CID was given the charge of investigations following a huge uproar over the incident.
