A man has been arrested in Greater Manchester following a social media post professing support for the New Zealand mosque attacks.
Greater Manchester Police said it became aware of the post and after “urgent enquiries” arrested a 24-year-old man in Oldham.
He was held on suspicion of sending malicious communications.
A spokesman for the force said on Saturday evening: “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.”
Forty-nine people were killed in attacks on two mosques in Christchurch on Friday. Brenton Tarrant, 28, has been charged with murder.
