Somebody drove off from a parts plant near North Charleston with 15 baskets of metal worth more than $54,000 Saturday, according to the Charleston County Sheriff's Office.

Investigators are asking for help finding out who did it.

Deputies were sent to Hesco Bastion at 2821 Azalea Drive Saturday morning to investigate a theft, according to the incident report. A worker told them he saw a white International flatbed truck loaded with baskets of joint pins parked beside a building about 5:45 a.m. He said he didn't think much about it until he and a co-worker heard the truck roar off and saw that it had left skid marks behind. That's when they realized they had been robbed, he told deputies.

The worker estimated the total cost of the stolen metal at $54,320.

The back gate was locked but could be pushed open without unlocking it, according to the report.

No suspects have been identified, Maj. Eric Watson said.

Anyone with information is asked to call the Sheriff's Office at 202-1700 or Crime Stoppers at 554-1111.
