The Manchester Police remain on high alert amidst reported threats against citizens in the wake of the arrest of the alleged leader of the Grey Ground Gang.
Commanding Office for Manchester Superintendent Wayne Cameron said two anonymous calls were made to the police yesterday (Mon).
Reports are that the threat has also been making the rounds on social media.
Police says the caller warned of attacks on civilians, if the reputed leader of the gang was not released from custody.
Superintendent Cameron says the alleged leader and another man were taken into police custody last week.
