An investigation is ongoing and charges are possible in a crash Tuesday where a car struck a group of bicyclists in Woodruff County, police said.

Arkansas State Police on Wednesday identified the driver of the car as 21-year-old Teagan Ross Martin of Newport. It happened on Arkansas 17 two miles north of McCroy, injuring seven of the 13 cyclists in the group.

"Martin has been questioned by State Troopers who are continuing their investigation," state police said in a statement. "The investigation will continue into next week and will subsequently be submitted to the Woodruff County Prosecuting Attorney for consideration of any charges against Martin."

The cyclists, described by police as "mostly teenagers," were on a cross-country trip from Charleston, S.C., to Santa Monica, Calif.

The Associated Press reported earlier Wednesday that five of the cyclists remained hospitalized, including one in critical condition.
