A Ukrainian model, who was the girlfriend of slain Russian opposition leader Boris Nemtsov, was questioned and interrogated for days in connection with the murder of the leader at a stone's throw from the Kremlin wall on Friday night, last week.
The 23-year-old, recognised as Anna Durytska, was with Nemtsov when he was shot dead. The couple was walking over the Great Moskvoretsky Bridge overlying the Kremlin when a gunman shot the leader multiple times from a car.
She was allowed to fly back to Ukraine after the Moscow Police questioned her for days, various reports suggested.
Durytska has recounted an emotional account of their last dinner in a chic Red Square restaurant and their walk at the nearby bridge. She has stressed that she didn't see the person in the vehicle who gunned her lover down, reports Associated Press.
"I don't want to answer questions about what happened on the bridge. I don't want to talk about this," the young model told TV Rain, The Guardian reports. "I am in a very difficult psychological condition and I cannot talk about this anymore now. I feel bad...I saw no one. I don't know where he came from, he was behind my back."
Nemtsov was shot four times in the back, just hours after he appeared in a Radio channel promoting an opposition rally that was scheduled for last Sunday.
Vadim Prokhorov, Durytska's lawyer said she was left emotionally drained by investigating officers.
"I've told them everything possible and I don't know why I am still on Russian territory, as I want to go back to my mum, who is ill, and who is in a very difficult psychological state," Durytska said, adding: "For three days, I've been driven around in police cars with guards to the Investiative Committee and questioned. And nobody has told me when I'll be let go and why I am being held here."
The model, however, was allowed to go home earlier on Tuesday, Ukrainian Foreign Minister spokesman Yvhen Perehyinis said, according to BBC.
Meanwhile, a CCTV footage of the incident has been released to the public by the authorities.
The clip - only image from a working camera in the area - shows a wide-shot of the couple walking in the bridge when the killing took place and the gunman's car speeding past the scene. The actual image of the shooting is, however, obscured by a snowplow, reports NYDaily News.
