A Fort Worth police officer who resigned last year after being arrested for keeping marijuana instead of turning it over as evidence has been sentenced to two years of probation.
Lamb's attorney did not return a call seeking comment.
Police began investigating Lamb after receiving a tip that he was possibly smoking pot while on duty, in uniform and in his patrol car.
An undercover officer posing as a concerned citizen gave Lamb about 3 ounces of marijuana. Lamb said he'd destroy it. Although he was supposed to take it to the police property room, the pot was later found in his home and personal car.
Prosecutors told the Fort Worth Star-Telegram that Lamb was not formally charged with tampering with evidence because the case didn't fit the charge's criteria.
He was arrested in April 2010 and resigned. Lamb had joined the department in 2002.
