KEY POINTS:
British police said they would investigate video footage of soul singer Amy Winehouse allegedly smoking crack cocaine.
Still images from the footage first appeared on the front page of The Sun tabloid and The Times newspaper quoted the head of Winehouse's record company saying that it may abandon plans to promote her in the key US market.
"Officers will be viewing the footage when we receive it from the media," said a spokesman for London police. The Sun said it had already handed over the footage, taken early last Friday.
