Two other shootings, one involving a police officer, took place Wednesday following a double shooting at Harrison and 24th streets that left one person dead and the other injured.

Police said that at 9:55 p.m., a 27-year-old man was shot in the foot at Mission and 19th streets. The victim was standing on the street when he was shot. No suspect information is available. The man suffered non-life threatening injuries and was driven to San Francisco General Hospital by a friend.

Another man was arrested early Thursday after a plain-clothes officer with the Criminal Investigations Unit was shot at multiple times while driving in an unmarked police car heading southbound on Highway 101. The incident happened at about 1:30 a.m. Thursday.

Police said that the officer was able to maneuver around the suspect’s vehicle, a 1990 Buick, to avoid being in the line of fire. The officer called for back up and started chasing the vehicle while shots were being fired. The driver of the vehicle exited the freeway at Cesar Chavez Street and headed northbound on Potrero and then westbound on 25th Street. The driver then pulled over on Bryant and 21st streets and three suspects jumped out.

The officer was able to arrest one suspect. A perimeter was established in the surrounding area as officers searched for the possible remaining two suspects early Thursday but police weren’t able to locate the suspects.

No injuries were reported. It’s unclear at this time whether the three shootings that occurred Wednesday night and early Thursday morning are related.
