Passage: On 22 December a public memorial service took place for Tucker, Bentley and Choate at St Paul's Cathedral. King George V was represented by Edward Wallington, his Groom in Waiting; also present were Churchill and the Lord Mayor of London. The crime had shocked Londoners and the service showed evidence of their feelings. An estimated ten thousand people waited in St Paul's environs, and many local businesses closed as a mark of respect; the nearby London Stock Exchange ceased trading for half an hour to allow traders and staff to watch the procession along Threadneedle Street. After the service, when the coffins were being transported on an eight-mile (13 km) journey to the cemeteries, it was estimated that 750,000 people lined the route, many throwing flowers onto the hearses as they passed.Identity parades were held at Bishopsgate police station on 23 December. Isaac Levy, who had seen the group leaving Exchange Buildings, identified Peters and Dubof as the two he had seen carrying Gardstein. It was also ascertained that Federoff had been witnessed at the events. The following day Federoff, Peters and Dubof all appeared at the Guildhall police court where they were charged with being connected to the murder of the three policemen, and with conspiracy to burgle the jewellery shop. All three pleaded not guilty.On 27 December the poster bearing Gardstein's picture was seen by his landlord, who alerted police. Wensley and his colleagues visited the lodgings on Gold Street, Stepney and found knives, a gun, ammunition, false passports and revolutionary publications. Two days later there was another hearing at the Guildhall police court. In addition to Federoff, Peters and Dubof, present in the dock were Milstein and Trassjonsky. With some of the defendants having a low standard of English, interpreters were used throughout the proceedings. At the end of the day the case was adjourned until 6 January 1911.On New Year's Day 1911 the body of Léon Beron, a Russian Jewish immigrant, was found on Clapham Common in South London. He had been badly beaten and two S-shaped cuts, both two inches long, were on his cheeks. The case became connected in the press with the Houndsditch murders and the subsequent events at Sidney Street, although the evidence at the time for the link was scant. The historian F G Clarke, in his history of the events, located information from another Latvian who stated that Beron had been killed not because he was one of the informers who had passed on information, but because he was planning to pass the information on, and the act was a pre-emptive one, designed to scare the locals into not informing on the anarchists.The posters of Gardstein proved effective, and late on New Year's Day a member of the public came forward to provide information about Svaars and Sokoloff. The informant told police that the men were hiding at 100 Sidney Street, along with a lodger, Betty Gershon, who was Sokoloff's mistress. The informant was persuaded to visit the property the following day to confirm the two men were still present. A meeting took place on the afternoon of 2 January to decide the next steps. Wensley, high-ranking members of the Metropolitan force and Sir William Nott-Bower, the Commissioner of the City Police, were present.
