KNIGHTSEN -- Sheriff deputies are looking for several armed suspects involved in a home invasion of a suspected marijuana grow operation early Thursday, authorities said.
The Contra Costa Sheriff's Office received a report of the home invasion on the 1400 block of Delta Road in Knightsen at 12:13 a.m., said spokesman Jimmy Lee.
Several armed suspects fled the area before deputies arrived, he said. An extensive search for the suspects turned up nothing, according to police. Investigators believe the property was used to cultivate marijuana.
They are asking anyone with information on this incident to call the sheriff's investigation division at 925-313-2600, send tips to email@example.com or call the anonymous tip line at 866-846-3592.
