Crime Branch sleuths on Tuesday arrested Lamboo Shakil, accused in the infamous J J Hospital shootout case and the trusted lieutenant of underworld gangster Dawood Ibrahim.

Lamboo Shakil alias Shakil Mursalim Shaikh, the 42-year-old associate of Dawood, had come to the metropolis to carry out the gang's activities, Mumbai Police Commissioner R S Sharma told reporters.

Police arrested the gangster, against whom the CBI had issued a red corner notice, at Kurla in northeast Mumbai.

They had laid a trap for Shakil after receiving a tip-off that Shakil, based in Dubai, is visiting the metropolis, Sharma said.

A police team spotted Shakil near the Feetwala compound in the area and after confirming his identity, arrested him under section 387 [threats and extortion] and 34 [common intention] of the Indian Penal Code.

After Dawood fled to Dubai in 1986, Shakil looked after the gang's operations in Mumbai till 1992, police sources said.

He is said to be involved in multiple offences, which were committed at the instance of Dawood, Sharma said, including  smuggling of gold and silver.

In 1992, to avenge the murder of Dawood Ibrahim's brother-in-law, his gangsters barged into a general ward of government-owned J J Hospital in broad daylight and opened indiscriminate fire killing rival gangster Sailesh Haldankar.

Following the J J shootout case, Shakil fled to Dubai in 1993, but continued to threaten businessmen in Mumbai for extortion, the police chief said.
