A man who was shot dead by the police at a railroad station could have called on officers to say that there was a gunman, said a guard dog.
David Joyce, 38, was shot by an armed officer at the Milton Keynes Central Station on April 1 after the Thames Valley police responded to the reports of a man who carried a gun.
An investigation by the Independent Police Conduct Office (IAPC) linked Mr. Joyce with a mobile number that called 999 to inform an armed man at the station.
The police force referred to the IAPC. An investigation into the death of Mr. Joyce was opened and postponed in the Milton Keynes Forensic Court on April 10.

An investigation by Watchdog said a call controller classifies the mobile phone number after the person called hung.
The handler spoke with the same man who said that the armed man was acting suspicious and “definitely” had a weapon, the IAPC said.
The records showed that the mobile phone number used to make the 999 call used to call the police before and was linked to Mr. Joyce, according to the guard dog.
CCTV’s images showed Joyce making a phone call while making the 999 call to the police, the IAPC said.
Joyce, who lived in Milton Keynes, but was originally from Galway in the Republic of Ireland, was armed with a meat knife with a 12 cm blade when he ran to two officers, said the guard dog.
He was then triggered at a short distance by a police officer from the Thames Valley of the Armed Response Unit.
The director of IAPC, Derrick Campbell, said: “We again extend our sincere condolences to the family and friends of David Joyce and all those affected by this incident.
“Constantly to keep your family informed of our progress.”
‘There is no criminal offense’
The Guardian dog said he had interviewed the officers involved, gathered a large amount of CCTV from the inside and outside the station, in addition to obtaining the video of the officers and the police video and the police vehicle.
He had also made house consultations in the statements of properties and close tasks of witnesses.
The officers remain as witnesses while the investigation remains ongoing, but there were no indications that none of them could have committed a criminal office or violated the behavior standards of the Police Police, added the IAPC.
