A man has been detained under the Mental Health Act this morning (Monday, 19) following reports of him acting suspiciously near Beachy Head.
Police were called around 8am and found a car grounded and abandoned near the driveway of the Belle Tout lighthouse.
They then began a search of the area along with coastguards, and a helicopter from the National Police Air Service.
The man was then found on the clifftops at the Seven Sisters and was followed until he entered the sea at Cuckmere beach.
He was persuaded to return to the shore and was then detained by officers.
