They were earlier found sleeping on the ground in Wong Chuk Hang near Water World Ocean Park by passersby who reported them to the police.
A team of officers from the police force and the Agriculture, Fisheries and Conservation Department were deployed to Shum Wan Road, less than a week after authorities last Friday announced they will capture wild boars in urban areas for "humane dispatch."
Police said 10 reports of wild boars were made yesterday including two swimming in a Sai Kung holiday camp and several others in North Point.
As of 9pm, two pigs were captured in the operation and a dozen more boars were spotted on the road. Police officers spotted five boars when they arrived, three of whom were behind a metal fence. They attempted to trap two of the boars after moving them to a corner but failed.
AFCD officers then tried to lure them with bread and 10 minutes later a vet shot them with dart gun with anesthetics to capture them while a third boar was put down along Shum Wan Road.
AFCD last Friday announced they will regularly capture boars in the urban area for "humane dispatch" to reduce their number and related nuisance.
Simon Chan Kin-fung, assistant director of the AFCD, said on Monday that the latest measure only targets wild boars in the urban area and will not capture those in the countryside.
He added that the AFCD aims to have five official operations per month to catch wild boars and will prioritize capturing boars in areas where there are large numbers of pigs.
Last month, an online video showed around 20 wild boars running behind a moving red taxi on Shum Wan Road at night.
Another scene from the same video shows that those wild boars seem to be eating something on the road while the taxi drove away slowly.
Hong Kong Wild Boar Concern Group's Roni Wong Ho-yin had previously said it is usual for wild boars to walk as a group.
Usually, they would hide in bushes upon seeing cars but boars might chase after cars when they have gained attachment from being fed by humans.
Yesterday morning (6/12) three residents of Tseng Tau Tsuen, Sai Kung, woke up to find that they had been burgled during the night.
