Officers from ACT Policing's crime prevention unit have embarked on an awareness campaign starting in schools in Tuggeranong and Belconnen.

Sergeant Bob Muir said, ''We're basically telling them to not be near anybody that worries them, not to accept gifts from them, not to accept lollies or money or things like that to get into the car with them.

''If they're walking together and someone does talk to them, not to respond to that and if they feel fear to run away.''

Police have ramped up their Kenny Koala program in light of the attempted kidnappings.

They are also warning children to be vigilant while on holidays.

''If they leave the ACT to go to the coast, for example, if they're on the beach or the caravan park, try to be in pairs,'' Sergeant Muir said.

Children are encouraged to have a plan should they be approached by strangers be it running home, to a nearby shop, to police or to a safe house.

Police stepped up patrols around schools in the aftermath of the most recent failed abduction, where a 10-year-old girl was grabbed on Knoke Street, near Gordon Primary School on April 3.

The neighbouring suburb of Conder was the scene of another attempted abduction four days earlier when a man tried to force a 13-year-old into his car at a bus stop.

Patrols were also increased on the north side of the city after a man made sexual advances towards a 12-year-old girl before trying to drag her into his vehicle.

In all cases the girls managed to escape unharmed. Police believe the incidents may be linked.

A series of newsletters aimed at a cross-section of children and school communities was also in the pipeline, Sergeant Muir said.

''It was something [the crime prevention unit] has talked about, and it's a way of us communicating with the kids at all levels,'' he said.

''Colleges would have a different message sent out than what a primary school would. And it also helps us liaise more closely with the school communities.''

Sergeant Muir and Senior-Constable Kenny Koala, a 25-year veteran of stranger danger campaigns, toured schools including Conder Primary over the past two days.

The campaign will continue today.
