Outlining the facts on Tuesday, prosecutor Philip McGhee said Clarke-Samuel had been drinking alcohol on the evening of the crash.
The rapper, from Woodford Green in east London, was said to be one and a half times over the legal limit.
McGhee said Tamang was crossing the road when he was struck by Clarke-Samuel’s car.
“Mr Tamang was catapulted into the air before crashing down on the roadway. He sustained catastrophic injuries,” McGhee said.
In a statement, the student’s family said: “We speak today with hearts broken beyond repair. Our only child, a precious soul, has been taken from us far too soon.”
