British police said Friday that they have arrested a 26-year-old man on suspicion of killing two sisters and their mother in a crossbow attack.

In a statement Friday, Hertfordshire Police said that they arrested the suspect on Thursday evening. He remains in a serious condition in a hospital.

Police previously said that Kyle Clifford was captured on Wednesday in a cemetery near his home in Enfield, around 15 miles (24 kilometers) from the scene of the crimes, following a near day-long manhunt. Officers who found Clifford recovered a crossbow and took him away on a stretcher from Lavender Hill Cemetery with undisclosed injuries. Police said no shots had been fired.
