British political leaders called for calm following violent protests over the death of 18-year-old university student Henry Nowak, who died while handcuffed by police after being falsely accused of racism.

Eleven police officers were injured during demonstrations as protesters threw rocks and garbage cans at law enforcement. The scenes prompted condemnation from government officials, with one cabinet minister describing the violence as "unacceptable."

Conservative Party leader Kemi Badenoch drew comparisons between Nowak's death and the 1993 murder of Stephen Lawrence, calling for the case to serve as a similar turning point. Badenoch characterized the incident involving the stabbed teenager as a moment requiring significant reflection and change.

The Prime Minister issued appeals for calm as tensions continued to escalate around the case. The death has raised questions about police procedures and the circumstances surrounding how the student came to be handcuffed before his death.

Details about the specific circumstances of Nowak's death and the nature of the racism allegations he faced remain under investigation. The case has drawn significant public attention and sparked debate about police conduct and procedures.
