Several incidents, which appear to have been filmed and uploaded to social media by the person responsible, have taken place this month.

They show the birds-eye view from a drone flying towards and then hovering above the Holiday Inn Express in Tamworth.

One clip, captioned "stink bomb drone drops on asylum seekers" shows an item being dropped from a height next to a man standing outside its front door.

It's accompanied by the song 'Hit Me With Your Best Shot' and has been viewed more than half a million times.
