Spray helps catch and convict burglars

LONDON, July 24 (UPI) -- British police are testing a new Welsh product -- a spray that leaves indelible marks on burglars, making it simpler to catch and convict them.

The science-based security system, sold as RedWeb Sentry, combines conventional alarm systems with a conspicuous biosynthetic substance called "i-powder" that cannot be removed for several days. The powder carries a uniquely-traceable DNA code to the owner's property.

Police say recent trials in three U.K. locations have resulted in 100 percent conviction rates, reported the Sunday Telegraph.

Each batch of spray contains a durable red dye and a powder containing strands of DNA, that can irrefutably link a burglar to the scene of the crime.

The spray was devised by Liz Williams, a former interior designer.
