Menlo Park police were shot at early Sunday morning in front of a house in the 1100 block of Hollyburne Avenue east of U.S. Highway 101 in Menlo Park.
One officer returned fire, said police spokesperson Nicole Acker.
No officers were injured, but one suspect received minor injuries and was treated at Stanford Hospital and released, she said.
Six people were arrested, Acker said. Three were booked into San Mateo County jail for parole violations. They are Fredrick Tippons, 31; Luis Mariscal, 26; and Raymond Bradford, 25, all of East Palo Alto. The other three suspects have not been booked as of yet, she said.
In addition to a gun that was recovered immediately, four more weapons -- two handguns and two rifles -- were found in a subsequent search of the crime scene, police said.
The incident began when police received a call at 1:16 a.m. Sunday (Dec. 18) that several people were in front of the house in the 1100 block of Hollyburne Avenue, including a man with a gun.
When police arrived, they found five to six people that matched the descriptions provided by the caller. Shots were fired at the officers and the people fled, Acker said.
Two people were immediately arrested, and one gun was recovered.
Officers set up a perimeter and called for backup. SWAT teams from Menlo Park, Redwood City and San Mateo County responded, as did the California Highway Patrol. They helped conduct yard searches, and four more suspects were arrested.
Police ask that any witnesses call the police department at 650-330-6300 or the anonymous tip line at 650-330-6395.
