A source close to Marcel said OK! online: “Marcel and his companion were driving in east London towards their favorite restaurant and they noticed people on mopeds approaching them.
“Whenever they stopped at a traffic light, the mopeds would stop next to them on either side of the car and just looked shaded.
“Then when Marcel and his friend pulled up in a side street to park, they saw the mopeds heading towards them again. Each moped had two people and they kind of went around the car.
The insider claimed that the attackers then drew machetes as they got off their mopeds.
“As Marcel opened the door of his car, two members of the gang got off the bikes and went looking for him with their machetes pulled, swinging them towards him. So he quickly closed the door and they locked the car from the inside, ”they explained.
The alleged assailants reportedly shouted “get out of the fucking car” before hitting the windows of the vehicle.
Marcel and his boyfriend walked away from the stage and went straight home.
The insider confirmed that no one was injured by the car’s exhaust with only a few minor scratches.
Marcel, who rose to fame as a member of the Blazing Squad before making the 2017 Love Island finale, was reportedly “shaken” by the incident.
It comes after Marcel went through a ordeal last month when he was taken to hospital in an ambulance after passing out of a fever.
As he fought for his life, doctors discovered the TV star suffered from diabetic ketoacidosis (DKA) – a serious complication of type 1 diabetes.
Marcel said OK! magazine: “I was throwing up, I felt dizzy. I lost weight, my face was sunken and you could see my bones.
“It’s because I have type 1 diabetes, but I only found out in the hospital when they asked me, ‘Do you know you have diabetes? I had no idea. ”
Marcel then spent a week in intensive care when “all the nutrients in his body” were depleted.
“I was about to be in a coma, but thanks to the NHS I got it right,” he said.
The health scare came just weeks before Marcel revealed his good news that his girlfriend Rebecca is pregnant with their first child.
Marcel asked the question during their baby’s gender reveal party.
The couple later revealed their first pregnancy came at the start of their 15-month relationship, but they tragically miscarried.
Revealing the moment he found out, he said OK! : “I was in the studio with my headphones on and she tapped me on the shoulder.
“She had loads of pregnancy tests in her hand, just to be sure. It was crazy! This is my first baby and I’ve been waiting for this for a long time, so it’s just crazy. “
