London: Greater Manchester Police on Sunday said that four people were arrested for allegedly inciting racial hatred by referencing the Friday's terror attacks at two mosques in New Zealand's Christchurch city which left 50 people dead.

Calling the incidents as "racially aggravated", law enforcement personnel in Queensway, Rochdale arrested a 33-year-old man and a 34-year-old woman after they received reports that a taxi driver was being allegedly abused and threatened by people, CNN reported.
