Mobile phone employee Mike Halligan committed suicide by falling from the seventh-floor restaurant, becoming the sixth person to do so since 2007. The 27-year-old Irishman was seen by tourist Fabian Graimann jump from the brasserie near Bank underground station "without hesitation." He died from multiple injuries including skull fractures after falling 80ft.
Graimann told an inquest: "I could see him fall towards the ground. As he hit the ground my view was obstructed by a bus in traffic."
Halligan left draft messages on his mobile in English and French saying: "I'm bored of life and even the future possibilities disinterest me, nobody's fault, nothing could be done to change it."
A further two messages read: "I no longer try to adapt myself to others. I'm not made for this world. I have cracked", according to a Mirror report.
He was visiting in London from Dublin on 16 January, taking a break from his Stuttgart home, where he was enrolled for a business computing degree. The following day he arrived to Coq d'Argent alone at around 2.50pm and ordered lunch before leaping from the rooftop terrace at approximately 4pm.
Coroner Dr Roy Palmer as well as City of London health and safety officers inspected the restaurant, which met all legal requirements for health and safety. Halligan's family were present at the Coroners' Court to hear that the Coq d'Argent restaurant went to "great lengths" to prevent suicides, such as installing a two-metre high wall and keeping security staff stationed near the terrace at all times.
Dr Palmer recorded that Halligan's death was suicide, saying: "I think if you jump off a roof in that way having left those messages I don't think there can be any doubt about it." The Irishman had no alcohol or drugs in his bloodstream when he died.
There have been several deaths at the restaurant, and a 6ft barrier was erected following the death of Nico Lambrechts in January 2013. Volunteers from the Samaritans have trained restaurant staff and security officers have been told to question anyone found alone on the rooftop bar.
Food blogger Wilkes McDermid tweeted about his last meal at Coq D'Argent before jumping to his death in February 2015. British Library manager Rena Begum, 29, took her life there in September 2012 after she received abusive Facebook posts for her westernised lifestyle.
In July 2009, Anjool Malde, Deutsche Bank employee, fell to his death, clutching a glass of champagne. In May 2007, Richard Ford, a City marketing executive, died after he jumping from the terrace.
