A man suffering from stab wounds stumbled into a San Diego barber shop Thursday morning, authorities said.
San Diego Police said 22-year-old David Mongero tried to take a backpack from one of two women waiting for a trolley in Encanto around 9:25 a.m.
The women tried to stop Mongero, so he pulled out a knife and threatened them, police say.
One of the women pulled a knife as well. As the two tried to stab each other, the other woman grabbed Mongero's skateboard and hit him in the head with it.
The woman with the knife then stabbed Mongero in the neck, according to police.
Mongero ran to a local barber shop in the 6200 block of Imperial Ave., where officers eventually took him into custody.
He was taken to a nearby hospital to be treated for a small laceration to the back of his neck, and then he was booked into jail for robbery.
