Two inmates, one of whom was a close aide of Chhota Shakeel, died as a result of a clash within the Mangaluru jail premises on Monday.
S Murugan, Mangaluru Police Commissioner told The News Minute that sharp objects were used in the scuffle.
The dead include Madoor Isubu aka Yusuf and associate Ganesh Shetty. Also, 12 other inmates and the police who tried to stop the clash have been injured.
Madoor Isubu is thought to have close links with underworld don Chhota Shakeel and was allegedly part of a ploy to kill former deputy prime minister L K Advani in 2010.
Isubu who hails from a village in Maddur near Mangaluru, had reportedly played a role in establishing links between the underworld and Naxals active in the area.
Though he was convicted for three years in a 2001 rioting case, Isubu got bail in 2003 and was absconding till 2010. It was after he went absconding that Isubu is supposed to have joined Chhota Shakeel's ranks.
Isubu was arrested in Riyadh by Interpol in 2010 and is being tried for two other murders amongst other criminal activities.
The reason for the clash between the two groups is yet to be confirmed. Investigations are underway, and security has been increased within the jail premises.
