At least two people have been shot dead by a man firing from a Mercedes convertible in southern Germany.

The silver car sped away after a woman (82) was killed near Ansbach in the state of Bavaria.

A cyclist was then shot dead in nearby Rammersdorf.

Police said the suspect had been arrested shortly afterwards at a petrol station. He was believed to have been acting alone.

"At the moment we have no evidence of accomplices but, of course, we will keep our eyes open," police spokesman Bert Rauenbush told TV news channel N24.

Petrol station employees detained the man after he went in with a weapon, according to the nordbayen.de website.

It reported that they had restrained him using cable ties to bind his hands.

The petrol station was cordoned off while emergency vehicles, a dog unit and police helicopters were sent to the area.

A farmer and another motorist were also threatened with a gun during the attack, police said in a statement. They were both unharmed.
