Police say a man who may be in the country illegally fled after reportedly causing a crash on I35 near West Friday morning.

The collision occurred at Tokio Road just south of West late Friday morning, and caused traffic to back up for about four miles until the scene was cleared around 11:30 AM.

Police say the man believed to be responsible for the 4-vehicle crash was towing a car and may have been hauling it to Mexico. They were still searching for the man Friday afternoon.

Thankfully, no serious injuries were reported.
