A San Francisco pedestrian died Thursday morning after a hit-and-run at Market and 5th streets, officials confirm.

The driver of a tractor-trailer left the scene after allegedly hitting the pedestrian and police say the suspect is now in custody.

"The driver is cooperating with police, but has not been arrested yet," according to KRON 4.

The San Francisco Police Department responded to a call for the vehicle collision involving the pedestrian at 5:42 a.m. The victim was taken to the hospital with life-threatening conditions and later died.

A section of Market Street at 5th was closed for hours as police investigated the incident; the street is now open.

The investigation blocked Muni streetcars and buses, including the F Market, 5, 6, 7, 9, 21, 27, and 31, in both directions. Coaches were being rerouted around the area.
