The first was reported at 4.20pm on August 3 when the residents of an address in Darenth Park Avenue returned home to find two men inside the house.
The men escaped through a window, threatening one of the victims when he tried to follow them.

A quantity of jewellery was reported missing.
Officers are also reviewing a report of three men trying to break in to a house in Princes View at around 1.10pm yesterday.
Police have not said they are linked but are continuing to investigate.
