A man has been detained in Greater Manchester for a social media post that allegedly supports the New Zealand mosque attack.
Officers said the 24-year-old from Oldham allegedly made a post making reference and support for the events in Christchurch. He was detained on suspicion of sending "malicious communications".
A police spokesman said: "This is a very difficult time for people. The events in New Zealand have reverberated around the world. Many people are in deep shock and are worried. It is at times like this that, as a community, we stand together. Where the law permits and people cross the line, we will take robust action, which may include arrest and prosecution."
Brenton Tarrant, 28, from Australia, is accused of slaughtering dozens of Islamic worshippers and injuring another 50 muslims. He ‘live-streamed’ the attack in New Zealand and outlined his anti-immigrant motives in a manifesto posted online.
