A man surrendered to police Thursday morning after a seven-hour standoff in Encanto.
The man threatened officers and at one point told police to enter his home and kill him Lt. Paul Rorrison with San Diego police said.
Police responded to the apartment at Flicker Street and Imperial around 11:30 p.m. after a call came in reporting an assault.
The woman said her boyfriend had knocked out her teeth and caused other injuries in the second-level apartment.
When officers arrived, the suspect barricaded himself in the kitchen.
The injured girlfriend, the suspect's mom, and married renters were hostages when police arrived. Officers got a ladder and helped those people get out of the building.
Officers then spent hours trying to talk the suspect out of the home. At times, they used a bullhorn.
"We know you're not stupid and we know you're not crazy. So we need you to put the knife down. We are trying to work with you,” one officer was heard during negotiations.
One neighbor said the tenants in the affected unit could be heard fighting around 10 p.m. Wednesday.
It wasn’t until just after 6 a.m. that the suspect surrendered peacefully to police.
The suspect's girfriend was not seriously injured officials said.
