Recently a man was jailed after a violent attack on his girlfriend in her own home. The lady managed to call 999 whilst the attack was going on and used the ’55’ destress code.
This system enables victims to press 55 if they are unable to speak to the police operator. This immediately informs the operator that there is a genuine emergency but the caller is unable to speak.
The operator records all that is going on and can also pin point the location of the call.
