A 31-year-old man appeared before Kwun Tong Court on Saturday to face a charge of murdering a taxi driver in Sai Ying Pun.
The prosecution requested psychological reports on the accused, Matthew Choi, before proceeding with the case.
Magistrate May Chung approved the prosecution's request and adjourned the hearing until October 29.
No plea was entered, and Choi did not apply for bail.
He is to be held in custody in Siu Lam Psychiatric Centre.
The suspect was arrested on Lamma Island on Wednesday, a day after the police started a manhunt following a fatal attack on the taxi driver.
The victim, 48, was stabbed in the neck and certified dead after he was rushed to hospital.
