SOUTH SALT LAKE — A man learned over the weekend that his ankle monitor wasn't a good hiding place when police say they found drugs there.

Police pulled over a man about 12:30 p.m. Sunday who was driving erratically, said South Salt Lake police detective Gary Keller. The man handed the officer a driver's license, which turned out not to be his, he said.

When he had the man step out of his car, the officer noticed a plastic bag with a white rock stuffed between his leg and ankle monitor. The white rock was confirmed to be cocaine, Keller said.

Dung Nguyen, 41, was booked into the Salt Lake County Jail for investigation of felony drug possession, giving false information to a police officer and was being held on an immigration detainer.
