Guido Grolle has been getting the bizarre delivery every day - including during the night and when he's getting ready for work first thing in the morning - but he's got no idea who the mystery sender is, the New York Times newspaper has reported.

Some of the pizzerias in the area have become aware of what is happening and have resorted to calling him after the order has come in to make sure it is correct.

Normally the unknown sender has been ordering the pizzas to his office in Dortmund but after the pizzerias cottoned on, the ''pizza stalker'' has been sending sushi, sausage and Greek food in a bid to mix things up a bit.

Police are now treating the incidents as stalking.
