"I proceeded through into the social work area and observed a male person seated on a padded bench seat ... the male had his head down and in his hands and appeared to be muttering to himself, 'I don't know why I did it, I don't know what came over me'.

"I asked the male 'What is going on here, what happened?'

"The male said 'I don't know what came over me.'

"I asked, 'What did you do?', he said, 'I just saw her, I grabbed her and tried to drag her into the toilet cubicle.'

"He said, 'I've been working on the telephone system'.

"I said 'you know you are in serious trouble and you can't leave, you have to wait for the police.'

"He said, 'Yeah I know.'

"The male asked, 'What am I going to do about work?', I said, 'That's the least of your worries'.

"The male seemed very withdrawn."

Mr Marshall said he wrote an incident report about the assault.

Mr Edwards continued to work for Telstra after the event, and was promoted a short time later.

A Telstra employee earlier gave evidence there was no record of the incident on their files.
