At around 1 in the morning, armed people entered into my house from the roof and I was scared because I didn't know they were police officers. And a couple of hours later police came and searched my house again," Arzu Eylul Yalcinkaya told the Anadolu Agency.   In a related development, Turkish interior minister has denied news reports appearing on American media that suspects travelled to the US from Turkey. Muammer Guler said Tamerlan Tsarnaev holding a Kyrgyz passport and three other people with the same surname arrived in Istanbul, Turkey, on July 9, 2003 and they left ten days later on July 19, 2003, adding that Dzhokhar Tsarnaev, the second suspect still at large, was not among the four visiting the country.
