An escaped lion was spotted running near a busy city road minutes before it savaged an elderly man and left him needing urgent hospital treatment.

According to reports, the animal attacked the 63-year-old because he was agitated by the frantic hooting and screams from motorists and pedestrians.

Before the attack, the beast was filmed strolling down Mombasa Road, just 1km from Nairobi’s international airport, Jomo Kenyatta, in a viral Instagram video.
