An Exeter woman has invented a plastic lid which she hopes to ease the problem of drink spiking and date rape by stopping drugs being easily poured into glasses.
Dawn Dines is marketing the plastic lids with the support of several police forces. They cost around 10p each and are being sold to pubs and clubs to give to customers.
National figures indicate that more than 60 per cent of spiking takes place in pubs and clubs, with women aged 18 to 30 most likely to be targeted.
Dawn Dines said of the invention: "I think for the community as a whole, it's going to make many people feel a lot safer.
"It's not a total prevention, but what it will do is make it a lot more difficult for someone to slip something into your drink."
