A cordon remains in place in Piccadilly Gardens after reports of a suspicious package were made.
A man aged 26 has now been formally arrested and is in custody.
Assessors, along with the fire service, will be attending to establish if the item is viable, (we now understand the suspicious package was not viable but the cordon will be in place until emergency services are happy that everything is safe)
Transport links including the Metrolink have been affected as a result of the cordon more information on public transport can be found HERE
As part of enquiries, Oldham Library has also been evacuated after reports of a suspicious device found there.
Officers are keeping an open mind and are exploring the possibility the incidents are linked.
More information will follow.
