A man wanted in 18 criminal cases and five of his accomplices have been arrested in Greater Noida after a gunfight with the Special Task Force (STF) of the Uttar Pradesh police, officials said on Wednesday.

The gang, which extorted money from several companies and acquired work contracts by pressurising them, was busted on Tuesday night, officials said.

The group’s leader, Pawan Nagar, was carrying a reward of ₹25,000 on his arrest, a senior official of Noida STF said.

“Following a tip-off on the gang’s movement in Ecotech 3, an STF team reached the spot, where an encounter ensued between the two sides. Six gang members, including Pawan, were arrested,” DSP, STF, Rajkumar Mishra said. Four firearms along with ammunition, 30 g brown sugar and two SUVs were seized from them.
