A viable explosive device has been found outside a Sinn Féin constituency office in Newry city centre.
Police said they received a report of a suspicious object in Monaghan Street on Sunday night, shortly before midnight.
A pipe bomb-type device was located.
Army ammunition technical officers (ATO) made the device safe and it has been taken away for further examination.
A Sinn Féin spokesperson said the device was left at the constituency offices of Infrastructure Minister Liz Kimmins and Newry and Armagh MP Dáire Hughes.
The area was cordoned off by police overnight but the cordons have since been lifted and the road has reopened.
A PSNI inspector said: “We’re grateful this morning to local people for their patience while we worked to make the area safe.”
Officers appealed to anyone who has dash-cam or CCTV footage from the area to contact detectives in Newry.
