AHMEDABAD: Six people were injured in a clash between two communities that broke out in Surat's Amroli late Thursday night.

The members of the two communities got into a fight in Kosad locality even as the police tried to intervene. Agitated mob unleashed itself on police personnel sent to control violence and pelted stones on them.

Police fired four rounds of tear gas to control the situation.

The administration said 40 people have been detained in connection with the violence and police has begun an investigation to unravel circumstances that vitiated the communal harmony.

The reason behind the clashes is yet to be established. However, sources said a minor dispute between two people resulted in a scuffle and later led to the clash.
