HUNDREDS of licensed premises and noisy neighbours were targeted in a joint operation between the police and council.
Twenty-one arrests were made in the crackdown, codenamed Condor, which involved dozens of officers.
They visited nearly 150 pubs, bars and restaurants to ensure they were complying with licensing laws and not causing a public nuisance.
Noise levels were checked at all, as well as at some private properties where disturbances were suspected.
Police cadets, aged 13 to 18, were deployed to see if licensees broke the law by selling alcohol, knives or tobacco to underage children. Twenty-one arrests were made for a series of incidents.
Officers also checked premises complied with other laws, including making sure door security staff are properly registered and shisha products and cigarettes were not smoked indoors.
A noise abatement notice was served on the occupant of an Edith Road flat after neighbours complained of loud rap music blasting out after midnight.
Councillor Greg Smith, Hammersmith and Fulham Council deputy leader, said: “Residents expect the council to enforce the rules properly and we take a zero-tolerance stance to anyone blaring out music in the early hours or selling alcohol or knives to children. Anyone found in breach of their licence in H&F can expect the full force of the law to descend on them.”
