Two people are being questioned in connection with the shooting of a man in midtown Manhattan on Monday, and there may be a mob connection, law enforcement officials tell NBC 4 New York. 

The man was parked near 49th Street and Ninth Avenue in Hell's Kitchen when the gunman came up to the window of his white van and fired at least three shots. Police believe he was targeted.

The victim, described as a construction site maintenance supervisor in his 50s, was not seriously injured and was walking after he was shot. He appeared to have a graze wound and was taken to the hospital.

The suspect ran west from the scene and got into a waiting car, according to witnesses.

Two Port Authority police officers searching for the man, based on a tip, apprehended one suspect Tuesday at a union training meeting in Queens, the official said. Another suspect was arrested in the Rockaways.

Law enforcement officials say one of the suspects has ties to the Gambino crime family.
