OAKLAND — Seven people, including a 15-year-old girl, were injured early Saturday in the Uptown district when police said a car deliberately slammed into them on a sidewalk.

The two occupants of the car fled on foot,  leaving the vehicle behind. The mass injuries happened about 1:37 a.m. Saturday in the 500 block of 18th Street, west of Telegraph Avenue.

The seven injured told police they had attended First Friday, which had ended a few hours earlier and were hanging out in the Uptown area. Police said most of those injured know each other.

Besides the 15-year-old girl, the other victims were three women, ages 18 and 19, and three men, ages 21, 22 and 23. All but the 22-year-old man are from Oakland. He is believed to be from Pittsburg.

According to initial police reports, the seven were on the sidewalk when a red Hyundai sedan deliberately drove into them, causing various injuries.

The victims all told police they had no idea why they were targeted and police also don’t yet have a motive for what happened.

Descriptions of the two car occupants who fled were not released.

Six of the victims were taken to hospitals by ambulance. The 22-year-old man got his own transportation to a hospital.

All but the 15-year-old girl and one of the 18-year-old women, who both suffered severe leg injuries, were expected to be released from the hospital.

Anyone with information about what happened may call police at 510-238-3426.

The incident follows two shootings in Uptown Oakland earlier this year. In April, an 18-year-old Vallejo man was shot and injured in an altercation and stray bullets also hit a neighboring apartment building, although no injuries were reported. A separate shooting in February left another man in critical condition with five gunshot wounds. Both shootings occurred in the 500 block of 17th street.
