A 23-year-old San Mateo man was arrested Wednesday after police said he entered the backyard and shed of a private residence and attempted to gain entry to the home.

San Mateo police responded about 1:20 p.m. Wednesday to the 400 block of Highland Avenue after receiving a report of a suspicious person.

Officers contacted Eduardo Ramirez-Acosta nearby, matching the initial description of the suspect, according to police.

Police said surveillance footage and witness statements showed Ramirez-Acosta entering the backyard and a closed shed, where he allegedly collected about $2,000 worth of items and placed them in a backpack and box.

Police further said the resident confronted Acosta as he left the shed, and he claimed to be affiliated with a cleaning company that had previously worked at the residence, which police later determined was false.

Ramirez-Acosta then left without the items, police said.

Additional surveillance footage showed Ramirez-Acosta allegedly attempting to enter the residence through multiple locked doors and windows, according to the San Mateo Police Department.
