A guy killed his friend for not replying to mentioned comment.

London, 16 December: 

A 20-year old man living in eastern part of London recently shot his friend near his friend's home. Just few minutes after the incident, police arrested him and took him under custody. At the station, the man claimed that his friend didn't reply to a comment where he had mentioned his friend on Facebook. The post where he mentioned his friend was actually a "Tag those friends..." type photo on a popular meme page.
