Police in Katerini, northern Greece, were investigating an incident involving a 76-year-old woman who claimed she was robbed after being drugged on Friday.

In her statement the 76-year-old alleged she opened to the door to a woman who was promoting a fruit juice brand.

The victim said she consumed the drink and lost consciousness, subsequently waking up to find that several items of jewelry had gone missing.

Similar incidents have been reported across Greece over the last few days, while three Roma women were arrested in Volos, central Greece, in connection to one of them.
