Telly addicts in Bradford who tune in without having a licence are being targeted after the net closed on offenders during Wimbledon.
Nineteen people in Bradford without licences were caught out as they watched the championship final between Goran Ivanisevic and Pat Rafter on Monday, July 9
Fifteen officers visited addresses in the Bradford area and the exercise is now set to be repeated.
A TV Licensing Authority spokesman said: "It was quite a scoop. We normally catch about nine people a day but on the day of the Wimbledon final we caught 19 in Bradford."
About 280 people a month are caught across the country and inspectors say that they are now planning more swoops during big television events in a bid to catch licence fee evaders.
The spokesman said: "We had a very successful operation with Wimbledon and there are other events that we will have officers on standby for."
Dramatic momemts in top soap operas and big sport events like Wolrd Cup 2002 are likely to be at the centre of future enforcement action.
The spokesman said: "We always used to warn people that we were in the area but that is going to change.
"From now on there is no warning and we will strike at any time."
The officer said that people in Bradford were no worse or better than those elsewhere in the country when it comes to evading licence fees.
"There was an incident in Yeadon where a TV licensing officer went to a house and was told there was no television on the premises but then saw someone leaving out the back door with it.
"Other times they hide the television but keep the remote control on the armchair or they refuse to answer the door even though you know they are in because you've seen the curtains move."
But offenders risk a fine of up to £1,000.
The spokesman said: "There is a serious message. Evaders face prosecution and a £1,000 fine.
"Our message now is to watch out during World Cup 2002."
