M4 in Berkshire reopens after 'welfare fear' closure
The M4 motorway in Berkshire has reopened in both directions after being shut for nearly four hours over fears for a man's welfare.
Police received a call from someone reporting a man near Oldrings Hill just after 0700 BST.
Traffic was held between junction 13 and junction 15 and drivers faced delays of up to 90 minutes while police closed the road.
Police said a man in his 40s had been detained under the Mental Health Act.
Drivers, who faced delays of up to 90 minutes, criticised the Highways Agency for lack of information from advice matrix signs.
The Highways Agency said diversions and closures had been put in place as quickly as possible and it had been doing all it could to reopen the motorway.
The motorway closed at about 0800 BST and reopened shortly after 1200 BST.
