A man has died at West Midlands worktop company Graniteland after stone slabs fell on him.
The incident happened at the Graniteland premises on Lyde Green, Halesowen, at about 3.20pm on Monday 30 November.
Medics fought to save the man, thought to be in his 40s, but he was confirmed dead at the scene.
West Midlands Police and the Health & Safety Executive (HSE) are investigating.
Local newspaper the Halesowen News quotes a spokesman for West Midlands Police as saying: "Police were called to reports of slabs having fallen on to a man at an industrial unit in Lyde Green, Cradley, at about 3.20pm.
"A man in his 40s was sadly pronounced dead at the scene.
"Enquiries to establish the circumstances are ongoing and the Health & Safety Executive has been informed."
The Midlands Air Ambulance attended along with two paramedics and the Midlands Air Ambulance Critical Care Car. Medics said when they arrived people were already trying to help the man.
