Police are still waiting for security camera recordings in their investigation of the horrific accident in which a passenger lost part of her leg after it became trapped in a moving walkway at Don Mueang airport last week.
Police said on Monday that airport management had been asked to provide the camera footage soon after the accident last Thursday, but investigators had still not received it.
Police will ask airport authorities if there was any problem preventing them complying.
Investigators were compiling witness accounts and other evidence to find out how the woman traveller came to be so seriously injured. Doctors were keeping the maimed woman in isolation to prevent any chance of infection, so police had still not been able to question her.
Management of Don Mueang airport had been cooperative with police in past cases, police said.
The investigation was proceeding and they were trying to speed it up, but at this stage the case was not considered as being delayed, police said.
On June 29, a 57-year-old woman lost a part of her left leg when it became trapped in the end of a moving walkway in the domestic terminal at Don Mueang airport.
