A paranoid schizophrenic with "psychotic beliefs" has admitted unlawfully killing a man and driving him to a police station.
Sukhwinder Singh, 40, was arrested after the body of 39-year-old Harish Kumar (pictured) was found in the front passenger seat of a BMW on August 10 last year.
The vehicle had been parked outside West Bromwich police station in the West Midlands.
Mr Kumar, of Willenhall, West Midlands, died from a single stab wound to the chest.
Wearing a red T-shirt, Singh, of MacDonald Close in Tividale, followed proceedings through a Punjabi interpreter and pleaded guilty to manslaughter by diminished responsibility.
At Wolverhampton Crown Court on Monday, prosecutor Nigel Power QC told the judge medical experts had said: "The defendant's psychotic beliefs contributed to and explained the killing."
Judge Michael Challinor told Singh: "Following your plea you will be sentenced on June 29 and I am going to direct you are produced in good time that day for sentence.
"I have no doubt you will co-operate now you are being medicated."
Paying tribute to Mr Kumar, his family said he was "a great, yet very humble man".
In a statement issued through police, a relative said: "He was always there to help and he will be sadly missed - I just can't believe that we've lost him."
Judge Challinor remanded Singh into custody until the date of his sentence at the same court.
