A contestant on ITV's reality TV show Love Island has described her anger and sorrow about the death of her friend Mike Thalassitis.
Montana Brown, who befriended the 26-year-old in the 2017 series, said: "I'm so angry at you for doing this because you are so loved by so many people".
Thalassitis was found dead in a park in Edmonton, north London, on Saturday.
His death is not being treated as suspicious.
Officers said they were called to a park near Latymer Way at 09:28 GMT to reports of a man found hanged.
'I'm so sorry'
Ms Brown said she knew her friend had been in a "dark place" in the months before his death and posting on Instagram, revealed the details of their last phone call.
She continued: "I'm so so sorry I couldn't do more to help you. I have so much love for you Mike and I will never forget you. Sleep tight darling and I miss you so much already 💙"
Alex Bowen and Rachel Fenton, who both also appeared on Love Island, tweeted their respects.
Ms Fenton tweeted: "I'm lost for words. My heart breaks for your family RIP MikeThalassitis."

'Shocked and saddened'
She said: "This should be a massive wake up call. I feel sick, reach out, sometimes to the most confident friend. We can only learn & try to change."
A spokesman for ITV, which produces Love Island, said: "Everyone at ITV2 and Love Island are shocked and saddened by this terrible news.
"Our thoughts and deepest condolences are with Mike's family and friends at this very sad time."
Meanwhile Stevenage FC, for whom Thalassitis began his football career, paid tribute to their former player.
"Everybody at Stevenage FC is shocked & saddened to hear the tragic news about former player Michael Thalassitis," the club tweeted.
"Our sincerest condolences go to his family & friends."
Thalassitis was born in Edmonton and played football for clubs including St Albans and Chelmsford.
During his football career he also made appearances for the National League side Ebbsfleet United in 2014 and most recently played for Margate in the 2016-17 season.
Paying tribute to their former player the club said: "Mike was a talented footballer and well-liked character at Hartsdown Park who will be fondly remembered by management, staff, volunteers and supporters at the club."
He also appeared on the reality show Celebs Go Dating in 2018. He split from The Only Way Is Essex star Megan McKenna late last year.
Last year, a contestant on the 2016 series of Love Island, Sophie Gradon, died aged 32. An inquest into her death was recently postponed.
