Police say they are searching for a man dressed in a black 'Trump for New Zealand' t-shirt, who stood outside Al Noor Mosque yelling racial abuse as worshippers left the Asr (afternoon) prayer on Wednesday.
A facebook post on the Muslims in Christchurch and Canterbury page says the man was outside the mosque for 15 minutes, saying "all Muslims are terrorists" and need to leave. He was also seen kicking and damaging the memorial items along the fenceline of Al Noor.
Last month, 50 people were killed in a terror attack on two mosques in Christchurch, with 40 of the victims killed inside the Al Noor Mosque.
According to the post, the police officers guarding the mosque "let the man go" claiming they couldn't arrest him as he didn't break any laws.
