ORINDA -- Police are crediting tips from alert citizens in an Orinda neighborhood for helping them apprehend four juveniles who they say are connected to at least one robbery in the city and possibly others in Lafayette.

All four suspects were arrested on suspicion of residential burglary and conspiracy Tuesday and taken to Juvenile Hall after being identified in a lineup of other suspects, police said.

The string of events that led to the arrests began around 11:05 a.m. Wednesday, when a resident on Muth Drive reported suspicious activity, police said. The caller said she someone get out of a vehicle and knock on the doors of homes while three other people remained in the car.

Minutes later, police received information that all four juveniles went to the back of a house on the street.

Armed with a description of the vehicle, Orinda police spotted it on Moraga Way and Orchard Road and pulled it over at Camino Pablo and Brookwood Road and detained the four suspects.

"I would like to commend the Orinda resident who quickly called police when she saw suspicious activity," Orinda Police Chief Jeff Jennings said in a news release. "This case would not have reached a successful conclusion without her."

A third Orinda resident called police while the four suspects were being detained, police said, and reported that a possible burglary occurred on Martha Road. Police confirmed the robbery took place, and put the four suspects

Police said they recovered cash, jewelry, cameras, musical instruments and weapons. Lafayette police are investigating whether the four were linked to any recent burglaries in that city.

Orinda police are asking anyone who witnesses suspicious activity to contact police dispatch at 925-284-5010. The line is available 24 hours a day, seven days a week.
