A man in Dallas watching a live webcam in the United Kingdom stopped a burglary after spotting thieves trying to break into a store.

The Beatles fan was watching a webcam on Tuesday of Liverpool’s Mathew Street, location of the Cavern Club, the club made famous by the band.

On his computer screen, he saw a group of men climbing a ladder and removing property from a store, reports BBC via CBC News.

He called police in Merseyside County and told them what he saw. Officers went to the scene and arrested three men on suspicion of burglary.
