BANGKOK: A scurrying robot dog named K9 dispenses hand sanitiser to curious children and wary shoppers - one of the more unexpected measures Thai malls are taking as the country relaxes virus restrictions.

The hi-tech hound is controlled using 5G, a technology promising super-fast internet speeds with immediate reaction times that is still in the initial stages of roll out in Thailand.

Mimicking an excited puppy, K9 roams around the popular Central World mall in downtown Bangkok, drawing the attention of delighted children eager to get gel from a bottle attached to its back.
