A police officer has apologised for a tweet about the Liverpool car park fire which has been construed as a reference to the Hillsborough disaster.
Northumbria Police received complaints after Curtis Ritchie, a serving constable, posted a message saying: "Have they started blaming the police yet????"
One person contacted the force to express concern, claiming it was a "disparaging remark about Scousers".
Another sent a message to the officer's bosses in Berwick, Northumberland, saying: "Can you please ask pc Curtis Ritchie (8873) to elaborate on his recent comments to the people of Liverpool & particularly families of the 96 ?"
The force would not name the officer involved in the Twitter row but said he had apologised.
A spokesman said:
The fire, which started in a car park next to the Liverpool Echo Arena on New Year's Eve, destroyed up to 1,600 cars.
