ANOTHER witness has come forward to contradict Opposition Leader Tony Abbott's denial that he intimidated a student rival by punching a wall next to her head during their student days, 35 years ago.

The man, a student at the time, said he was outside the Student Representative Council's offices photocopying when ''Abbott's famous flying squad of goons crashed down the stairs, threw me against the wall, kicked in the doors of the SRC and started creating havoc''.

The man, who says he was not involved in the SRC election, said it was extremely scary.

''I saw Abbott throw a punch at Barbara Ramjan, but didn't see it land … when next I saw her, she was in an extremely shocked condition, leaning against the wall … I thought he had actually struck her, but I can see that was simply my assumption and rationalisation.''

The witness wishes to remain anonymous but says he is willing to sign a statutory declaration.

Mr Abbott has denied the event.
