A teenage boy fled from his home screaming ‘he’s stabbed me’ in a Christmas Day horror that left two women dead and another man hurt.
Neighbours said the 17-year-old, who has not been named, suffered wounds to his head and chest in the attack in which the women, aged 38 and 24 also died, while a dog was also fatally knifed.
The nightmare unfolded as Wallace and Gromit was being broadcast on BBC1 on Christmas day evening and last night a 49-year-old man was being questioned in connection with the incident.
Officers were called to a block of flats on Santa Cruz Avenue in Bletchley near Milton Keynes by residents after they heard screams and saw the teenager covered in blood run outside calling for help.
One local told MailOnline: ‘I heard screaming and shouting looked outside and the boy was outside saying ”he’s stabbed me”. He was covered in blood and had wounds to his chest and head.
‘There was a woman on the balcony screaming for help and saying she couldn’t breathe and then the guy who did it ran out of the flats, got into his car and drove off but police were there within seconds and we told them where to go and he was caught.’
Another neighbour showed MailOnline CCTV footage of what looked like a white pit-bull limping away covered in blood and police later said the dog was taken to a vet but did not survive.
He added:’It’s not what you expect around here, it’s pretty quiet and not what you expect on Christmas Day of all days. It’s really knocked everyone because it is so quiet around here.’

Locals said the fatal stabbings took place in a top floor balcony and an England flag could been seen fluttering from the handrail of the two-storey building and there was also a bloodied handprint clearly visible on the metal.
Police were also examining the front door of a house opposite the apartment block, which was also blood stained and one of the victims is believed to have knocked there to frantically ask for help.
As officers carried out their door-to-door investigation, residents also left floral tributes at a corner close the scene while others tied bouquets to the fence of a park opposite the apartment block.
MailOnline has been told that the younger victim was originally from Nuneaton, Warwickshire, and had lived at the flat with her partner for several years and her partner in his 20s was also hurt.
Detective Chief Inspector Stuart Brangwin, of Thanes Valley police, said:’ We have launched a double murder investigation, which may be concerning to the wider public; however, we have made an arrest and are not looking for anyone else in connection with the incident and the parties are known to each other.’
