Police in the north west investigated more than 100 incidents last year that involved social networking internet sites.
Information given to the ‘Journal’ under the Freedom of Information Act show that between April 1 last year and the end of March 2012, Facebook was mentioned in police incident investigation logs a total of 111 times within the PSNI’s G District - an area that includes Derry, Strabane, Limavady and Magherafelt.
Micro blogging site Twitter was mentioned only once during police investigation.
Earlier this year Police in Derry warned that someone will be killed unless young people stop organising fights via social network sites.
In early March it was revealed that police were investigating three fights arranged via Facebook, two of which had been organised for Derry’s Ebrington Square.
At the that time PSNI Neighbourhood Constable Shona Holmes said: ”Parents need to closely monitor the social media internet sites their children are using and talk to them about the dangers of getting caught up in this sort of dangerous and antisocial behaviour.”
