Police have hidden 100 emergency trauma kits around the Square Mile of the City of London in case of a sudden terror attack.
The City of London police is training 60 officers to use packs that are filled with specialist medical equipment and hidden in various locations.
The locations are plotted on a map so the police control room is able to make use of them in the event of a major incident.
Inspector Chris Hay, of the City of London police, said: "The purpose of the scheme is simple.
"We want to boost the ability of our frontline police officers to treat casualties in the event of a major incident.
"Unfortunately the threat to the UK from international terrorism is ‘severe’, meaning an attack is highly likely.
"As we have seen over the past year in the UK, the first aid treatment which is carried out within the first few moments following an attack can be life-saving.
"By having our officers trained, it means that we can respond rapidly to these emergencies and can hopefully save lives.
"We hope to develop and continue our officer training and hope to increase the coverage of the packs throughout the City."
Acting Sgt Ron Henry, who organised the training for his City of London Police colleagues, said: “The first week of training has been very successful.
"We now have 12 fully trained officers who can use the emergency trauma packs.
"Over the next few months we will train more officers from our Uniformed Policing unit so that 60 in total will be trained to an enhanced first aid level and be able to use them."
