All the suspects are males and artisans aged between 25 and 30.
At a media briefing after the tour of the area, Mr Duker said the suspects would be handed over to the appropriate authorities for investigation and possible prosecution.
He urged the Weija-Gbawe Municipal Assembly to work closely with the police to arrest owners of illegal projects ongoing in the area.
He entreated the Assembly to demolish all illegal structures within earthquake zones.
The National Disaster Management Organisation, 2017, earmarked some parts of the Region as ‘imminent risks’ areas and ordered the demolition of illegal structures at the Weija Hills to avert potential mudslide.
