Four teenagers were arrested in connection with two Monday night robberies, one in which a 35-year-old man was stabbed with a knife in the Mission district, police said.
The robberies occurred about 15 minutes apart at 15th and Dolores streets and 18th and Sanchez streets.
The victim in the robbery at 18th and Sanchez streets was a 37-year-old man, police said. He was accosted from behind at around 10:45 p.m., held in a bear hug and robbed of his backpack, camera, iPod, and bicycle, police Officer Albie Esparza said. The victim was not injured, police said.
While cops responded to that robbery, a witness called 911 reporting a robbery in progress at 15th and Dolores streets, Esparza said. In that heist, the 35-year-old victim was accosted from behind, stabbed, and robbed of his backpack, he said.
He was transported to San Francisco General Hospital with non life threatening injuries, police said.
"He received several cuts and lacerations to his back," Esparza said.
Cops in the area found four teenage suspects between ages 15 and 17 walking on 14th Street near Guerrero Street, Esparza said. The suspects were positively identified by the victim in the first incident and also by a witness in the second incident, he said.
The stolen items were recovered, Esparza said.
Three of the suspects are San Francisco residents, and the fourth, a 17-year-old boy, is from Lodi, Esparza said. They are not being identified because they are minors.
The suspects were transported to The City's youth detention center.
