The Tottenham Outrage of 23 January 1909 was an armed robbery in Tottenham, North London, that resulted in a two-hour chase between the police and armed criminals over a distance of six miles (10 km), with an estimated 400 rounds of ammunition fired by the thieves. The robbery, of workers' wages from the Schnurmann rubber factory, was carried out by Paul Helfeld and Jacob Lepidus, Jewish Latvian immigrants. Of the twenty-three casualties, two were fatal and several others serious, among them seven policemen. The two thieves killed themselves at the end of the pursuit.
