The former football pro rose to fame on season three of the popular reality series in 2017.
The Metropolitan Police issued a statement saying: "Police were called to a park near Latymer Way, N9 at 0928hrs on Saturday, March 16 to reports of a man found hanged. Officers and the London Ambulance Service attended and found a man, aged in his 20s, deceased."
As reported by Express.co.uk, authorities indicated the death is not being treated as suspicious.
The tragic news comes just two months after his best friend Danny Cutts passed away.
Reports suggest that he had also been grieving the death of his grandmother who recently passed away.
Tributes from fellow reality stars and media personalities quickly flooded social media, with many of Mike's Love Island co-stars criticising producers for the lack of support offered to contestants in the aftermath of filming.
Dom Lever, Mike's love rival from his stint on the show, took to Twitter to voice his sadness at the 26-year-old's passing and blasted TV executives for failing to stand by participants.
"You get a psychological evaluation before and after you go on the show but hands down once you are done on the show you don't get any support unless you're number one," he wrote.
Lever's sentiment was echoed by a slew of other celebrities, including Love Island season two's Malin Andersson who lost her newborn daughter Consy earlier this year.
"If I didn't have a strong head on me that my mum passed down to me, I wouldn't have been able to cope with this all. But not everyone is like this. PLEASE IF YOU FEEL ALONE, OR SAD, OR STUCK REACH OUT TO SOMEBODY!" she begged.
Mike's death comes nine months after former Miss Great Britain and Love Island season two contestant Sophie Gradon took her own life aged 32 following a long battle with depression.
Gradon's on-screen girlfriend Katie Salmon shared a message of warning for aspiring reality stars in the wake of yesterday's news.
In a lengthy post on Instagram stories, the star wrote: "Speechless. RIP Mike... Today I feel different. last night I was numb, not because I knew Mike deeply but because nobody is listening to us.
"Have spoke out on the news. My platform. My YouTube. The papers. Everybody suffers with some sort of mental health issues and we are by no means more important than any other human, but for some reason because we are in the public eye it seems to give you all assurance that you can say and speak what the f**k you want about us. Including papers.
"Online bullying is real you never know what anyone is going through."
