Police have warned that any supporters found in possession of flares and pyrotechnics at Liverpool's Champions League clash with Manchester City could be sent to prison.
As revealed by Sportsmail on Monday, City officials expressed 'serious concerns' after it emerged that a group of Liverpool supporters are planning a hostile reception for their team coach ahead of the April 4 first leg.
A poster circulating on social media urged fans of Jurgen Klopp's side to congregate on the streets close to Anfield more than two hours before kick-off to give Pep Guardiola and his squad a 'coach greeting' - and called on them to arrive armed with pyrotechnics.
