Police in Finland believe they have caught a car thief from a DNA sample taken from a mosquito they noticed inside an abandoned vehicle. Finding the car in Seinaejoki, north of Helsinki, police saw that the mosquito had recently sucked blood and decided to send the insect for analysis. The DNA found from laboratory tests matched a man on the police register. The suspect denies stealing the car and says he was just hitch-hiking a lift with a man. A prosecutor must now decide if the sample is strong enough for charges to be pressed.
