LONDON (AP) - The teenagers who stabbed wealthy Joao Da Costa Mitendele to death before burgling his home were careful to conceal the crime. They used a pretty girl to gain access to his apartment, where they wore rubber gloves while committing their crimes.

What they hadn't counted on was the phalanx of video cameras that silently watched and recorded them leaving the local subway station, buying those gloves and approaching 45-year-old Mitendele's apartment in suburban north London. The same cameras caught their hasty return journey to the station half an hour later.

The tapes sealed the fate of the so-called ``Honey Trap'' gang when played in court earlier this year. Seven of the group were convicted of offenses ranging from manslaughter to conspiracy to rob and sent to jail for a minimum of seven years each.
