The misconduct hearing followed an audit of those who accessed files relating to the case to see if they had had a good reason to do so.

In total, 104 officers and police staff were initially identified as having potentially accessed files without legitimate cause.

A majority of those of were subject to forms of discipline including written warnings and “reflective practice” training sessions.

In most cases, those who accessed the files did so “out of curiosity”, Mr Cundy said.

“When spoken to, they were remorseful, apologised, admitted poor judgement and were keen to engage in training.

“We know that honest mistakes can be made, and the most serious outcomes relate to those who were deliberately evasive or tried to avoid accountability. Those actions are not compatible with the values of the Met.”
