Niagara Regional Police say they have arrested the man believed to be driving the car that crashed into the Welland Canal early one morning last month.

Six people were injured when the 2009 Audi A4 they were in was driven into, roughly, a metre of water on Jan. 21st. The driver, police say, struck a tree before crashing into the canal. Officers say that portion of the canal was drained several weeks prior.

First responders airlifted a man in his 20s with serious injuries, while the other passengers, also men in their 20s, went to a local hospital.

Police issued an arrest warrant for a 23-year-old man of no fixed address last week on four charges, including two counts of dangerous operation causing bodily harm.

Police say the man turned himself in at the Niagara Falls district office yesterday and is being held in custody pending a court appearance on Thursday in St. Catharines.
