A suspect is under arrest in connection with a New Year's Eve shooting at a bar in the Old Sacramento area that killed two people, police said Tuesday.

The 22-year-old was among three people wounded Monday evening after a shooting that occurred as people gathered to watch fireworks to celebrate the New Year, authorities said.

The suspect's injuries and those to a security guard and a 30-year-old woman are not life threatening.

Police say it started as an argument inside the bar at about 9:38 p.m. Monday that escalated and became a physical confrontation. When an employee tried to break up the fight, he was shot, as were the woman and another man.

That man, 35, and the employee, who was in his 20s, died at the scene after suffering multiple gunshot wounds.

Authorities say an armed guard near a side door at the bar heard the gunshots and got into a gunfight with the suspect and both were wounded.

The armed suspect ran out of the bar toward a street crowded with holiday revelers but was caught quickly by officers chasing him, police said.

Police are not identifying the suspect because of the ongoing investigation.

Afterward, police canceled the midnight fireworks show that was expected to draw as many as 40,000 people.
