ORLANDO (AP) — Someone shot at four cars on one of central Florida's busiest highways early Monday but there were no injuries, authorities said.

The shootings resembled ones from last week when 15 cars were shot at while motorists were driving along Interstate 4, as well as on Interstate 95. No one was injured in those shootings.

The Orange County Sheriff's Office in Orlando tweeted that Monday's shootings took place on Interstate 4 near the border between Orange and Osceola counties.

The location is dozens of miles from where last week's shooting took place in Volusia County, near Daytona Beach.

The sheriff's office was seeking the public's help in identifying the shooter.
