Armed officers were deployed to Welshpool on Tuesday to assist with an arrest on Foundry Lane.
It is believed that armed officers were en route to the town following reports of a 35-year-old man making threats to kill over the phone.
A full firearms authority was issued and readers reported increased police activity with the force chopper also active over the town, but we are told the arrest was made prior to the armed officers’ arrival.
The arrested man remains in custody.
