Two men committed an armed robbery in Tottenham, London, and led police on a two-hour chase, partially by tram, that ended in the perpetrators' suicides.

The robbery, of workers' wages from the Schnurmann rubber factory, was carried out by Paul Helfeld and Jacob Lepidus, Jewish Latvian immigrants.
