Update, 11 p.m. Sunday: A San Francisco woman's missing dog, presumed stolen, was found safe late Sunday night after a stranger appeared to walk away with it in the city's Japantown district.

A San Francisco woman spent the weekend searching for her dog after a stranger appeared to take it.

Surveillance video shows a man lurking near Lily, a golden retriever, in front of a building in Japantown. The man calmly unclips the dog and leads her away.

Owner Jennifer Seta said she left her dog leashed to a pole outside of a market on the 1700 block of Post Street. When she exited the market, she discovered Lily was missing.

San Francisco police officers searched the area to no avail.

Owner Jennifer Seta says she is heartbroken and just wants Lily safely returned.

"I have strangers texting me, telling me that they're looking for her, people asking if they can print flyers, people coming up to me and asking, 'Hey, have you seen a lost Golden?' And I'm like, 'That's my golden.' Pretty amazing response from the community," Seta said.

Lily and the man were last seen getting off a Muni bus at San Bruno and Harkness avenues Saturday.

The dog was stolen from outside Nijiya Market in Japantown.

Anyone who has seen the dog should call 911. Anyone with information regarding the whereabouts of Lily, should contact San Francisco police at 415-575-4444.
