An 18-year-old man was stabbed in the face, back of the head and chest after a riot erupted outside a Holloway youth club.

Police tried to rescue Charles Avhanvhondo as he lay in Sheringham Road outside Martin Luther King Youth Club – but were forced back by dozens of battling teens.

After the hour-long riot was brought under control, Mr Avhanvhondo was taken to Whittington Hospital for emergency treatment.

But cops were met with a “wall of silence” as they tried to trace those involved.

Meanwhile, days before the 1987 general election, the race for Islington South and Finsbury was neck and neck.

Polls had Labour incumbent Chris Smith and the Alliance’s George Cunningham at 36 per cent each.

It was a reflection of the 1983 election, when Mr Smith won the seat from Mr Cunningham by just 363 seats.

In the event, Mr Smith retained his seat – again with a slender majority of 805.
