Cantonal police in Solothurn are threatening to release CCTV images of a man pushing another man into the train tracks at Olten unless he turns himself in.
The incident happened at the end of January. Witnesses say the two men were arguing and one pushed the other onto the tracks as a train was approaching.
The victim was able to save himself before the train arrived and no one was injured.
Police say if no one has come forward by the 1st March, the pictures be given to the press, pixelated at first – and then without the blurring later.
