ACT Policing Senior Constable and team leader of online Troy Roberts said despite good intentions, people who nominate a name or post a tip-off to the wall of ACT Policing's social media sites can put personal safety at risk.

"Most people on Facebook have their name and their picture so if they post [a name], obviously that person who was nominated knows who that person is now," Senior Constable Roberts said.

"We will say to the person we are deleting your post, it is for your protection . . . but rest assured your information has been forwarded to the investigators."

The launch of Facebook for ACT Policing on February 20 this year came a few days earlier than planned, following reports of a baby in a stolen car.

The story received the biggest uptake to date, sparking a public search for the vehicle and baby.

The incident generated more than 215,000 views, 2500 shares, 1000 likes and over 300 comments.

"We launched a couple of days early because that type of incident was exactly the reason we went into social media.

"In that case, Twitter and Facebook played a huge part in what we did on that day.

"It's a great communication tool, and it's a great tool to exchange information quickly but as far as reporting a crime, there are timeliness issues and there's nothing better than talking to the person involved."
