The Latest on a triple shooting at a San Francisco park (all times local):

1:25 p.m.

San Francisco police say the shooting of three people in a popular park full of children and sunbathers appears to have been a "targeted incident."

Police spokesman Robert Rueca said Friday that investigators were looking into whether Thursday's shooting was gang-related, among other possible motives.

No arrests have been made, and two of the three people who were wounded are still hospitalized.

Rueca says police have stepped up patrols around the park in the rapidly gentrifying Mission District, which is transforming from a gritty area to a popular neighborhood of expensive homes and trendy bars and restaurants.

San Francisco police will station two officers at a popular Mission District park during the day and night following a shooting that wounded three people and sent others running for safety.

KTVU reports that it's not clear when the extra patrols will begin at Dolores Park.

Police say the shooter or shooters remain at large. A motive has not been determined for the Thursday shooting.

Authorities say one man remained in critical condition Friday morning and another was treated and released.

Another hospitalized victim is a teen and no details were being released.

Police continued the hunt for a gunman who opened fire in a Mission District park crowded with parents, children and tourists on a warm summer's day, wounding three people and sending panicky people running for safety.

Investigators were trying to determine a motive for Thursday's attack, which turned normally peaceful Dolores Park into a chaotic scene of bleeding victims and fleeing visitors.

A man who identified himself only as Hatter said the attack came after park regulars confronted about a half-dozen men who were shouting and acting threateningly on a park bridge.
