Where can I watch "The Face at the Window" (2004)

I have been looking for this movie for a long time but have not been able to find it anywhere. Apparently it was released in Sweden and the UK but isn't available! Here is the plot of the film:

A young boy called Erri has run away from his village in Yugoslavia, and ended up in Britain. He is taken to the detention, where he is questioned by Mirko (Serge Soric). He escapes, and is found by Victoria and Robert, who smuggle him to their house. They keep him in next door's attic, thinking that he is in danger. Victoria contacts the Balkan Support Group, saying it is for a school project, and is allowed to talk to Julian (Aleksandar Mikic). She hints about Erri, then leaves. When Mirko and a detective come looking for Erri to keep him safe, Erri runs off with Robert, and a girl named Lesley. They hide out in a warehouse, and the next morning, Julian arrives at Victoria's house. He lets her use his phone to call Robert, and Julian then heads off to find Erri. Victoria tells the police just in time, and they manage to reach Erri before Julian and his crowbar reach him. Erri has to give evidence against Voynic, a warlord who killed everyone in Erri's village.

If anyone else has seen this movie, let me know and where it is available to watch (if anywhere).
