OFFICERS from the Marine Support Unit of the Met Police’s Thames division have spent two days crawling through the mud of the River Thames foreshore at Erith.

The officers were watched by gathering crowds last weekend as they carried out a hand search of the mudflats at the Erith pier, next to Morrisons supermarket off Erith High Street.

Police confirmed the officers were searching for a knife they believe may have been used in the murder of Barnehurst television repairman Graham Boyne, 41.

Mr Boyne was found dead at his Parkside Avenue home on April 24 last year.

He had been stabbed 27 times.

His estranged wife Maria, aged 30, and her lover Gary McGinley, aged 24, of Franklin Road, Bexleyheath, are currently on trial at the Old Bailey, where they both deny murdering Mr Boyne.

Geoff Cooper, aged 58, of Wharfside Close, Erith, was one of those who watched the search.

He said: “On the Sunday, I told them they were searching for a needle in a haystack, but then one of the officers told me they had just found it.”
