Amy Winehouse husband arrested over "trial fixing"

LONDON (Reuters) - The husband of troubled British soul singer Amy Winehouse has been arrested in an investigation into perverting the course of justice, days before he is due to go on trial for beating up a bartender.

Pictures in Friday's Daily Mirror newspaper showed Winehouse, 24, kissing husband Blake Fielder-Civil, 25, before he was led off in handcuffs by plainclothes police during an overnight raid at an apartment in East London.

Police said five people had been arrested following a tip-off by the Daily Mirror -- two 25 year olds, one 22 year old, a 19 year old and a 36 year old.

All were seized in connection with an allegation of perverting the course of justice.

Fielder-Civil goes on trial on Monday for inflicting grievous bodily harm with intent over allegations he and another man beat up bartender James King.

The Mirror tipped off police after it received evidence that Fielder-Civil and friends were trying to pay King not to testify.

A spokesman for Winehouse said the singer had no comment over the arrest.

Earlier on Thursday evening, police crashed into her house in North London with crowbars, but neither she nor Fielder-Civil were there.

Winehouse, who scored a hit last year with the song "Rehab" about refusing drug and alcohol treatment, has been dogged by allegations of substance abuse, no-shows at concerts and erratic behavior.
