North Wales Police says public safety is its prime concern, as officers "try to coax two young men off a roof in Wrexham."
There are trained negotiators at the scene, and Chester Street in the town remains closed.
The safety of the public, police officers and the offenders is our prime concern.
We appreciate that the situation is causing some disruption, but we would ask for the public's understanding and cooperation in allowing our trained negotiators at the scene to bring this incident to a safe and peaceful resolution.
