Two policemen who stopped for cups of tea at a McDonald's before attending an emergency call for a suicidal woman will face a misconduct hearing.
Fahima Begum, 22, was found hanged after a friend called 999 saying she had sent him a suicidal text message.
The call to the ambulance service was referred to police.
An investigation found Met officers Tony Stephenson and Gavin Bateman bought hot drinks then waited 24 minutes before contacting the friend.
The police watchdog said the PCs' delay in attending her home in Poplar, east London, was "significant".
An inquest in November 2015 found Ms Begum was dead before the 999 call was made.
The Independent Police Complaints Commission said it was given the second-highest grading by call-handlers, meaning officers must get to the scene within 60 minutes.
Regulations state however they should attend as soon as possible, the watchdog added.
Now, there's no denying that the officers were downright sloppy in their response to a 999 call. But that such calls are 'graded' and the second highest grade, which one assumes might be considered at least a bit urgent, allows 60 minutes to attend seems downright dubious to me. apart from such an officially lackadaisical approach to an emergency call, if the officers were told that this was 'only' a second grade call then it is human nature that they will assume they have that 60 minutes before criticism arises. To put a 60 minute response time on an emergency call would suggest, to me at least, that it wasn't really an emergency in the first place. It sounds like a couple of police officers are going to get hung out to dry in order to disguise a crap policy on call handling and response.
