The construction site where the body of missing Barnsley seven-year-old Conley Thompson was found had been checked by police during the night and found to be locked up.
Conley was reported missing at 10.10pm last night, after having last been seen at his home at about 6pm.
South Yorkshire Police declared the situation a ‘critical incident’ and drafted in 50 officers to search for him.
The force tonight revealed officers had checked the same construction site where Conley was later found during their search in the night.
But they found the building securely locked with a large perimeter fence.
Police are working with the Health and Safety Executive as part of their investigation into the tragic accident.
Detective Chief Inspector Dave Stopford said: “At 10.10pm on Sunday 26 July, South Yorkshire Police were alerted to a report that a seven-year-old boy, Conley Thompson, was missing, having last been seen leaving his home address by his mother at approximately 6pm.
“The investigation was declared as a critical incident and around 50 officers were drafted in to search for Conley.
“Extensive, methodical and structured searches took place throughout the night involving specially trained search officers.
“The construction site, where Conley was sadly discovered by construction workers this morning, was checked by officers during the hours of darkness and found to be securely locked with a large perimeter fence.
“The investigation continues into the cause of Conley’s death and we are working with the Health and Safety Executive as part of that investigation.”
