They have been carrying out patrols in the Railway Park area of the Tyrone town.
"There is significant evidence of anti-social behaviour in this area including numerous broken bottles and make shift dens," said a PSNI spokesperson.
"We would urge parents to check where their children are this weekend. Work will be ongoing over the coming weeks to enforce on street drinking and discourage anti-social behaviour In this area.
"We want to work in partnership to reduce this anti-social behaviour and ensure this park is an area that everyone can enjoy."
