SHOPKEEPERS are urged to ban under-16s from buying flour or eggs to help stamp out anti-social behaviour this Halloween.
Posters have been produced by police and fire officials for businesses to put up saying that proof of age may be needed before the goods are sold to young people.
It comes after a 30-year-old man was left partially blinded in one eye after yobs threw an egg at him from a car last month.
As reported, the victim, who works at the University of Portsmouth, was walking along Hampshire Terrace, Southsea, when the egg was thrown, hitting him in the face.
He had to undergo surgery to remove a piece of eggshell that was embedded in his left eye, scratching his cornea and leaving him with blurred vision.
Police say they will ramp up patrols in known troublespots during the Halloween weekend to crack down on anti-social behaviour.
Householders are also urged to put up a poster in their windows if they do not want trick or treaters to knock at their door.
It reads: ‘Sorry no trick or treating here – please respect our wishes.’
Chief Inspector Jerry Patterson said: ‘Every year our force control room receives calls from people who have been frightened or disturbed by trick or treaters.
‘Police officers will be targeting hotspot areas to ensure that people are respecting others in their local neighbourhood.’
Last year police received 5,479 non-emergency calls between October 29 and 31 – a 14 per cent drop on the previous year.
