Before being appointed at Great Britain Hockey, Halliday had previously been a specialist firearms officer in the Metropolitan Police and was a member of the team involved in the De Menezes shooting on July 22 in 2005 at Stockwell Underground Station.

The Brazilian had been wrongly believed to have been one of the fugitives who had been involved in a failed bombing attempt the previous day.

It came two weeks after 52 people were killed in three suicide bomb attacks in London the day after the city was awarded the 2012 Olympic and Paralympic Games, which also saw over 700 people injured.

De Menezes was shot several times by firearms officers at the station, with the Brazilian dying at the age of 27.

Due to the sensitivities of the case in Brazil and Halliday’s peripheral role in the incident, Great Britain Hockey and the British Olympic Association have agreed that he will not travel to the Rio 2016 Olympic Games as part of the management team.

“I would like to place on record our thanks to Andy for the dignity and professionalism which he has shown throughout this process,” said Sally Munday, Great Britain Hockey chief operating officer.

“Andy is a highly valued member of our team, although he won’t be travelling to the Olympics with the team, he will continue to play a very valuable role in their preparations.”

Halliday is due to work alongside the rest of the management team to help prepare the players ahead of the Games, as the British team look to improve on their fourth place finish at the London 2012 Olympic Games.

 “Whilst I am obviously disappointed not to be going to the Olympic Games, I have known of this decision since last November and respect the process that has been followed and the decision itself,” said Halliday.

“The performance interests of the team continue to be of paramount importance and I am focussed purely on helping the team prepare for Rio 2016.”
