"All members of the British police forces are shocked at the savagery of this attack. In any democratic society it is the role of the Police to protect basic human rights and our two French colleagues died protecting free speech," ACPO's Vice President Peter Fahy said in a statement.
ACPO and the UK's Police Federation has urged all police forces across the country to hold ceremonies in remembrance of those killed in the terror attack in Paris and stressed the importance of cooperation and public support to prevent the spread of extremist ideologies.
On Wednesday, three men attacked the office of the satirical magazine Charlie Hebdo in Paris, claiming the lives of 12 people and injuring 11. Seven suspects have been arrested so far, with a nationwide manhunt for two gunmen still underway.
The magazine previously received threats from Islamists for publishing caricatures of the Prophet Mohammad.
