A dramatic video has emerged from Mexico of a topless man said to be on drugs jumping several metres from a bridge to escape police and walking away as if nothing happened.

The video, captured by a driver as the man fell into the motorway ahead of him, shows the man landing and walking towards the filmer's car with police lights visible on the bridge above.

The man, reported to be named Hilario Guajardo, is said to have taken "a cocktail of drugs" and escapes apparently uninjured after the jump while escaping armed police - though was eventually captured.
