Metropolitan Police Commissioner Sir Mark Rowley defended officers involved in a knife attack arrest after Green Party leader Zack Polanski criticized their use of force. Rowley said he was "disappointed" that Polanski shared a post condemning how police handled the incident.

The clash centers on how officers arrested a suspect in a knife attack. Polanski characterized their actions as excessive force, prompting the Met chief to push back against the criticism. Rowley did not detail specific objections to Polanski's post but expressed frustration with the characterization of officer conduct.

The dispute reflects broader tensions over police tactics and oversight in London. Police forces operate under scrutiny over use-of-force incidents, while departments argue officers must act decisively during violent crime responses. Rowley's defense suggests the Met views the arrest as justified and proportionate to the threat posed.

Polanski's intervention brought a political dimension to the incident. As Green Party leader, his public criticism carries weight in London political circles and adds pressure on the police force to justify operational decisions.

The exchange does not indicate whether any formal investigation into the arrest will follow.
