Santa Cruz police are celebrating the arrest of the man they say is behind a string of graffiti tags throughout the Bay Area.

Cops say that Derek Murphy, 21, of Petaluma, is the tagger behind the series of "BERG" and "GREB," police said in their blog.

"It is time to get up on your feet... do "The Wave" and tip your cap to Detective Brian Warren," police wrote.

It's Warren who's credited with chasing down a series of leads that began on June 10 of this year. The BERG and GREB tags began showing up on city parks and police vehicles right around that time.

Tips from San Francisco police led to tips from Sonoma and Napa counties and eventually the identification of Murphy as the tagger, according to the police account.

Murphy was arrested Dec. 15, and a second suspect is not yet identified pending his arrest.

Murphy may be responsible for tags "throughout the west coast from Bakersfield to Seattle," according to police.

Cops say Murphy is responsible for "numerous tags... along Bay Area freeways."
