(CNN) -- A vehicle was intentionally driven into three students outside a high school near the southern French city of Toulouse Friday, injuring them, the country's interior ministry said.

A driver was arrested after the collision, and the Toulouse prosecutor has been called to investigate, the ministry said.

The vehicle accelerated as the students crossed a road, the interior ministry said.

The collision happened outside Saint Exupéry high school in the Toulouse suburb of Blagnac, according to CNN affiliate BFM TV.

Initial information about the conditions of the injured -- identified by authorities only as Chinese students -- conflicted. The interior ministry said the students were lightly injured; BFM reported that two were in serious condition.

Toulouse Prosecutor Pierre-Yves Couilleau said Friday evening that two students remained hospitalized and one had left the hospital.

The driver has a history of mental illness, the interior ministry said in a statement. The incident doesn't initially appear to be related to terrorism, the interior ministry said.
