A man has been convicted of attempted murder for attacking a Sikh trainee dentist with a machete in a racist assault intended as revenge for the slaying of a British soldier by Muslim extremists.

Zack Davies struck Sarandev Bhambra in the head with a foot-long blade in a supermarket in Mold, Wales, in January.  Witnesses said they heard Davies shout "white power" and "this is for Lee Rigby." Bhambra was seriously injured.

Prosecutors said white supremacist material was found at Davies' home.

A jury at Mold Crown Court found 26-year-old Davies guilty Thursday. He will be sentenced in September after undergoing psychiatric assessment.

Rigby was run down with a car and stabbed to death in a London street in May 2013 by two men inspired by Islamic extremism.
