A crazed wild boar smashed through a garden gate and then attacked the resident.

The rampaging hog emerged from nearby woodland before charging onto the property in Chiang Mai, northern Thailand.

CCTV shows how the panic-stricken owner tried to lock out the beast but it simply headbutted the white metal gate to force its way through.

With the gate hanging from its hinges, the pig leaped through a barbed wire fence and attacked the terrified man who tumbled backward before running away.

He was shaken but not seriously hurt.

The man said he checked the property's fences to try and prevent any boars returning in the future.

Thailand has between 1.5 million and two million wild boars. The population is thought to be stable, although there are some concerns about habitat loss and fragmentation. They are most common in the northern and eastern regions of the country.
