A man described as a “prolific” mail thief was arrested in Irvine this week, police said Friday.

Tanoah Daniel Marsh, 33, of Anaheim, was arrested and booked Wednesday after a search warrant was issued in Santa Ana and authorities found thousands of pieces of stolen mail.

Police say Marsh allegedly had an elaborate locksmith set up, which he used to create keys for himself and others to access mailbox and buildings.

Investigators are working with U.S. Postal Service inspectors to identify victims in this case and return mail to rightful owners.

Police provided images of some of the evidence seized, including keys, locks, tools and mail.

Police told KTLA they had been looking into the case for the last couple of months, and are looking into whether Marsh shared his keys with other thieves.

No further details about the alleged crimes was released.
