The Hollywood sign got a little green over New Year's, according to CNN.

A prankster managed to change the iconic sign overlooking Los Angeles early Sunday to read "Hollyweed," said L.A. Police Officer Christopher Garcia, who works in the agency's security service division.

The vandal -- who police think is probably a man -- used tarps to change the O's in the sign to E's, he said.

The vandal was caught on security-camera footage between midnight and 2 a.m. local time, but police can't tell his race or height because it was dark and raining, Garcia said.

The "Hollyweed" sign remained up until around 11 a.m., when authorities took down the tarps used to change the lettering.

Estevan Montemayor, a spokesman for Los Angeles City Councilman David Ryu, whose district includes the Hollywood sign, had earlier promised the iconic sign would be restored to its normal state.

"We don't know who did it but park rangers are going up there very soon to take down the draping that was put on top of the 'O' to alter the sign," Montemayor said Sunday morning.

There are sensors at the sign that trigger an alarm for police, but because the sensors are only in certain areas of the letters, it's possible to avoid them. There's a road accessible to the public by foot and car behind the sign.
