He swung the machete at Mr Gosling two more times but missed.

The two robbers fled with Mr Gosling’s air rifle and were spotted by police carrying it on Longroyd Avenue, Beeston.
Both were arrested and officers later discovered the machete dumped in a garden on the same street after the incident in the early hours of January 31.
Mr Gosling had to undergo hospital treatment for damaged cartilage in his left ear.
Moran, of no fixed abode, admitted robbery, unlawful wounding and possessing an offensive weapon.
He was jailed for three-and-a-half years.
Patrica, aged 23, of Tong Drive, Wortley, admitted robbery and was sentenced to a community order with two years supervision plus 280 hours unpaid work.
Moran’s lawyer Andrew Haslam said his client has been a “model prisoner” during 185 days behind bars on remand since the incident.
Jailing Moran, Judge Kerry Macgill told him: “You left the premises and returned a few minutes later, brandishing the machete and threatening to cut the chest of the complainant.
“Not surprisingly he hands over the air rifle.”
