United flight diverted over security

The pilots reported a sequential beeping noise that they feared could be a potential explosive device, triggering a full-scale security response.

After a thorough sweep of the plane and luggage, no hazardous materials were found, and the incident was deemed non-threatening.

More than 150 passengers were safely evacuated, though several reported minor injuries during the slide deployment.

The aircraft has since been cleared for service, but the source of the beeping noise remains under investigation by federal authorities.
