Lily Allen could be fined if she smoked during her Liverpool concert
An investigation has been started by Liverpool City Council into whether singer Lily Allen was seen smoking while performing at a concert.
The council said it became aware of the alleged incident after a newspaper review mentioned the singer smoking at her concert in Merseyside on Wednesday.
The council said it was liaising with the Echo Arena venue over the inquiry.
If Allen had been smoking she would have been in contravention of workplace legislation, a council spokesman said.
The council has appealed for anyone who witnessed the singer smoking on stage to contact them.
If Allen is found to have been smoking during the event, both she and the concert venue could be fined.
The BBC was awaiting a response from the venue, while a spokesman for the singer said they would not comment on the situation.
