A man was arrested after shooting five men Saturday night during a fight that broke out at a birthday party in Pittsburg, police said.

Officers responded just before 11 p.m. to the 100 block of Madoline Street for reports of a shooting, said Capt. Rathnesh Raman of the Pittsburg Police Department.

Upon arrival, police discovered five adult men with gunshot wounds and the shooting suspect, who was being held down by other partygoers, Raman said.

The victims were transported to a nearby hospital and were in stable condition.

The suspect, a 23-year-old Oakley resident, had arrived at the birthday celebration with a group of people and was asked to leave, Raman said. A fight then started.

The situation escalated when the suspect, who was not identified, pulled out a firearm and began shooting, Raman said.

The suspect was detained by others at the party until police arrived. He was arrested on multiple felony counts, including assault with a deadly weapon.
