THE HAGUE, Netherlands (AP) — Police say that a 37-year-old man suspected of involvement in two deadly stabbings in the southern Dutch border city of Maastricht knew at least one of the victims.

The suspect was arrested late Thursday in a mosque in Maastricht shortly after a man and a woman were killed and two other people were injured.

Police spokesman Jack van Kleef said Friday that the suspect knew at least one of the victims, but would not elaborate as it is still under investigation.

Van Kleef says the suspect is in hospital recovering from light head injuries and has not been questioned.

The victims' identities were not immediately released. Van Kleef would not confirm local media reports that the victims were of Syrian descent.

Police have ruled out terrorism as a motive.
