Yahoo! hinders sex case inquiries

Internet companies including Yahoo! are hindering police investigations into child abuse by closing down the undercover identities used by officers to trap paedophiles.

British child protection police habitually pose as children online, using false profiles to ensnare abusers trying to groom girls and boys for sex.

But the companies say they will shut down all bogus identities on their sites even if they know they are being run to catch paedophiles.
