TMZ is reporting that the L.A. County Sheriff’s Department put out a “possible suicide attempt” APB on producer Timbaland just before 5 p.m. PT yesterday after his family feared he would harm himself over the recent theft of a $2 million piece of jewelry.

A helicopter and squad cars went on a hunt for the rapper/producer’s Escalade, according to sources.

Per TMZ…

Timbaland was on the phone earlier in the day with his brother-in-law … deeply upset about something. We’re told one of the things that was eating at him was a theft at his Malibu residence a day before. Someone had stolen a crazy expensive Jacob & Co. watch — valued at $2 million — and Timbaland suspected it might have been someone he trusted.

Timbaland left his home yesterday and began driving. Family members couldn’t locate him, became extremely worried and called the Sheriff’s Department.

We’re told the helicopter located the Escalade, ground crews pulled Timbaland over and began talking to him. At some point they put Timbaland in a patrol car and took him to his residence, where they continued speaking with him and family members.

Deputies called for paramedics to come and evaluate Timbaland. After the evaluation, paramedics determined Timbaland was not a threat to himself and left.

We’re told the Sheriff’s Department is investigating the theft of Timbaland’s jewelry and they have possible suspects.

This news comes as Timbaland is set to headline an outdoor concert in the Malaysian capital Kuala Lumpur, as part of the global “Arthur’s Day” Guinness brewery celebrations, scheduled for Sept. 23 to 24 across the globe.

According to Billboard, Timbaland will be joined by Thai-American hip hop band Thaitanium and Malaysian rock acts Pop Shuvit and Mizz Nina, at the live event, which forms part of a simultaneous worldwide concert series held in honor of Arthur Guinness, founder of the Dublin, Ireland-based Guinness brewery.

The Malaysian leg will be staged at Kuala Lumpar’s Sunway Lagoon Resort. Last year’s inaugural “Arthur’s Day” event saw over 60 artists, including Black Eyed Peas and Estelle, perform around the world.

Jamaican dancehall and reggae artists Shaggy, Lady Saw, Beenie Man, Mavado and Bounty Killer have been confirmed for the Caribbean leg, with concert sites to be confirmed shortly, according to organizers.
