Toronto police say one man is in custody after an apparent domestic violence incident at a North York residence.Investigators were called to a home in the Sheppard Avenue West and Jane Street area just after 5 p.m. on Saturday for what was initially described as “unknown trouble.”When they arrived, police found a woman suffering from serious injuries. She was taken to a trauma centre via an emergency run. The woman’s age and the seriousness of her injuries was not immediately known. A man was arrested at the scene and police say an edged weapon was recovered. Investigators say the man and woman are known to each other and they are not looking for any other suspects at this time.
