Police took one armed man into custody at around 8:30 tonight after the suspect allegedly robbed someone at gunpoint earlier in the day and then ran for refuge into a house on Shotwell near 23rd Street, according to police.

The incident brought out dozens of police officers, including hostage negotiators and a SWAT team.  Police barricaded off the perimeter bordered by 22nd and 24th streets and Shotwell and South Van Ness.

Witnesses said that 12 police officers entered the Shotwell house near the empty lot of the now-closed Delano Market. No shots were fired and the armed suspect was in the house alone, according to police.

One officer from a tactical team said that there had been a robbery and the suspect fled and barricaded himself in the apartment. Officer Albie Esparza said the robbery had occurred around 4:30 p.m.

It was unclear where the robbery of the victim occurred.

Police arrested the suspect and put him into a police car at around 8:30 p.m. and by 9:20 p.m. police officers were pulling down caution tape and allowing neighbors back onto to the street.

One witness said that the owner of the house where the suspected was barricaded was waiting outside in the street while the whole incident played out in front of him.

The suspect was alone in the house and his surrender was negotiated.

One neighbor said at least one officer had been on scene since 5:30 p.m.

As late as  8:30 p.m. police were prohibiting pedestrians and cars from going through the blocked off streets.

One woman trying to get beyond the barricade at 23rd and South Van Ness had to wait until police got clearance and then walked her to her apartment.

Earlier in the evening, we depended on a tip from a reader and on the Twitter feed below. Thank you reader, @Aleks_Mist and @natesayer.
