Danielle Gonsalves, a Hayward resident, was arrested Aug. 23 on suspicion of mail theft and trespassing and other alleged crimes, according to police.
Officers began an investigation June 23 regarding a package that had just been delivered to a Fremont resident's porch, police said.
Surveillance video captured Gonsalves grabbing the package and running away, according to police.
Gonsalves admitted to stealing the package from the Fremont porch, police said.
A different surveillance video that showed Gonsalves allegedly stealing a package from a Hayward-area porch was featured on a local news broadcast that aired June 27, according to police.
Police said mail theft can lead to identity theft. For protection, residents should use a locking mailbox, give mail to a letter carrier or send it from the post office, avoid sending cash and let senders know if expected mail doesn't arrive, police said.
