Ray Boccino

Ray sends Niko after the rats who hit his Algonquin meet. Niko hunts a Korean target through Algonquin's K-Town subway, fights through commuters, and finishes the job below ground.
No Way on the Subway is a mission in given to protagonist Niko Bellic by Italian mobster Ray Boccino from the Drusilla's restaurant in Little Italy, Algonquin, Liberty City.
The mission begins with Ray and Phil Bell informing Niko that the money and the diamonds are missing (Johnny Klebitz stole the money during the bungled deal in the museum and Luis Lopez stole the diamonds). Ray orders Niko to deal with the bikers from The Lost MC, who are hanging around on Vauxite Street in Northwood.
Niko heads to an alley just off Vauxite Street, where he confronts the two bikers. The bikers escape and Niko steals a nearby bike to give chase. A short time later, the two bikers ride off a bridge on Uranium Street and down onto the subway line, with Niko following them. The chase continues on the Algonquin Inner Line subway tracks as they head towards North Park Station and then East Park Station, while dangerously swerving between tracks to avoid oncoming subway trains.
Shortly after passing East Park Station, the chase transfers to the Algonquin Outer Line, heading towards the Algonquin Bridge while still on the subway tracks. The unnamed biker is killed shortly after dropping onto the line (either by Niko or by crashing head-on into a passing train). After the unnamed biker has been killed, another biker, Jim Fitzgerald approaches an accident on the subway tracks before leaving the railway line and getting back onto the street. Eventually, Niko catches up to Jim and kills him. Niko phones Ray to inform him of the bikers' death.
