A man convicted in the 1993 serial blasts case was arrested early on Thursday for knifing another person at a tea stall near the JJ Marg junction.
Police said Ehtesham Shaikh (38), who was convicted and spent 10 years in jail in the blasts case, stabbed Ashraf Khan (30), a Maharashtra Navnirman Sena activist, for staring at him.
According to statements recorded by the police, Khan and a friend were discussing all those they had enmity with and referred to the killing of police informer Irfan Chindi (who was shot at JJ Marg last year).
Then Khan happened to mention Shaikh. The two realized that he was standing right there.
“That is when both looked at Shaikh and he misunderstood," one of the witnesses told the police.
A patrol van passing by saw the ruckus and arrested Shaikh with the knife in his hand. Khan was rushed to JJ Marg hospital where he is undergoing treatment.
Khanderao Patil, senior inspector of JJ Marg police station, said the two had a falling out earlier and that Shaikh was looking for a chance to get back at Khan.
Ehtesham was arrested on the charge of attempt to murder and has been remanded in police custody for a week.
