Officers said the parcels were thrown over the prison wall at around 9.30am on December 23. An investigation was launched following the incident.
Police said they believe the man in the CCTV images could 'assist with enquiries'. The photos were posted onto the GMP Salford Facebook page as part of an appeal.
