A 32-year-old man has been arrested over the death of a man on his doorstep in North Lanarkshire.
Samuel Hamilton, 56, was found seriously injured outside his home in Bellshill on Wednesday night.
He had been on his way home from a relative's house before he was found by his mother at about 23:30. Emergency services attended but Mr Hamilton was pronounced dead at the scene.
Police have been gathering CCTV footage from the area.

"Specialist officers are providing support to her and other members of Mr Hamilton's family.
"Our thoughts are very much with them at this extremely difficult time."
