SAN LORENZO -- Burglaries are on the rise and authorities are asking residents to be alert.
Sgt. Bret Scheuller with the Alameda County Sheriff's Office said a dozen robberies happened in the unincorporated area in April, more than twice the amount from the previous year.
"For the year, we are actually down in the number of home burglaries -- 32 compared to 37 -- but in April we saw a good jump," said Scheuller, adding the numbers for May have not been updated.
Scheuller, as well as the San Lorenzo Village Homes Association, are telling residents to be aware of suspicious activity in their neighborhood and make sure windows and doors are locked when people are not home.
Most incidents have been similar, with the thieves first knocking on the door to see if anyone is home and then finding unlocked doors and gates leading to the backyard of homes. The perpetrators then enter through a door or window in back of the house.
Scheuller said residents should make sure doors or gates leading to their backyard are properly locked.
"Do everything you can to make your home a less attractive target," Scheuller said.
He also recommends writing down serial numbers of valuable property, such as laptops, stereos and televisions, so if they are stolen they may be more easily found.
In most cases, Scheuller said, the thieves have stolen between $2,000 and $5,000 worth of property.
Scheuller said April's spike in burglaries
"Burglary numbers ebb and flow a lot," said Scheuller, adding however, no one wants to see the numbers continuously grow.
Anyone who spots suspicious activity should call 911 or the sheriff's office nonemergency number at 510-667-7721.
Scheuller said if using a cell phone in the area, call the sheriff's office number, as 911 calls made from a cell phone must be rerouted.
