“At 10.00 a.m. on the morning of Tuesday 4 May, two individuals wearing red arm-bands presented themselves at Apartment No 1, 2 Plaza del Ángel. They were received by comrades Berneri and Barbieri, whom they told not to shoot as they were friends and there was nothing to fear. Our comrades replied that, as antifascists who had come to Spain to defend the revolution, they had no reason to be shooting at antifascist workers.
The two individuals then left and were seen from the window to enter the premises opposite belonging to the UGT union. At around 3.00 p.m. the same day, five or six individuals wearing the same red arm-bands as the ones who called that morning, plus steel helmets and shotguns called to the apartment again, stating that they had authority to effect a search. Seeing that the search was thorough, comrade Tantini handed three rifles over to them, stating that they had been left there for safe-keeping by three militians who had turned up on leave from the Huesca front. After collecting the rifles, the UGT personnel and policemen left, just two of the latter staying behind to complete the search. Papers found in comrade Fantosi’s room and a few books and maps from comrade Mastrodicasa’s room were taken away. As for comrade Berneri’s room, given the volume of the material there, they made off with only a portion of it, stating that they would be back with a car. As they left, they warned our comrades not to venture outside and to keep away from the windows, unless they wanted to get themselvers shot. The searchers, upon being questioned, replied that they had had reports of armed Italian anarchists in the apartment.
