The cause of a business fire in York County is under investigation, and officials say it could be arson.
Firefighters were called to the RCR Machine Shop along the first block of Baltimore Street in Glen Rock around 5:20 a.m. Wednesday.
Officials say the fire started in two trailers hauling cars outside the shop, and the flames then spread inside.
A classic Porsche 911 that was stored in one of the trailers was destroyed. A classic Ferrari, which was in the other trailer, was not damaged.
