FA set to launch another investigation after West Ham fans thrown smokebombs

West Ham face yet another investigation by the Football Association after a supporter set off smokebombs during Saturday's 1-0 defeat by Tottenham on Saturday.

Sportsmail understands that a 21-year-old man, Renaldo Haldeda, has already been charged by the London Metropolitan Police for throwing a missile onto a football pitch and criminal damage.

He has been bailed to appear at Thames Magristrates' Court on November 5.

The West Ham support appeared to set off the smokebombs when they thought Javier Hernandez had equalised in the second-half of the game. The celebrations were cut short, however, by the sight of the assistant referee's offside flag.

The club's bubble machine, which goes off when West Ham score, also spurred into action too soon so a section of the stadium was decorated by celebratory bubbles and red smoke as the home side continued to trail.

The Public Order Act of 1986 makes it an offence for a person to have in their possession any firework, flare or smokebomb at a sports' event. Smoke bombs create sufficient heat that it can cause burns to people who attempt to remove them.

The FA will now request observations from West Ham ahead of a possible charge. Considering all supporters are searched before entering the stadium, it is also surprising that it was possible to smuggle the pyrotechnics into the stadium.

West Ham were charged by the Football Association in July following the shocking scenes during a 3-0 home defeat by Burnley in March, when supporters invaded the pitch, confronted captain Mark Noble and also surrounded the director's box before coins were thrown, striking vice-chairman David Sullivan above the eye.

The FA's hearing is still to be concluded for the events against Burnley, as the CCTV footage continues to be scrutinised but West Ham are braced for a significant fine.
