The new manager of Hull’s Transport Interchange says staff working there are continuing to face violence and provocation on a regular basis.
Dan Fox said cracking down on crime and antisocial behaviour was one of his top priorities.
Last year Interchange operator TransPennine Express closed a public access route from Anlaby Road in a daytime trial in a bid to tackle problems in the immediate area.
The move prompted a public outcry as well as criticism from Hull''s three MPs and city councillors.
The gates were re-opened before the end of the scheduled trial period and Mr Fox said there were no immediate plans to shut the access on a more permanent basis.
But he said antisocial behaviour and vandalism at the Interchange were still ongoing issues.
Speaking at a council scrutiny meeting, he revealed one staff member had recently been sexually assaulted while on duty while another had been bitten in a separate incident.
"We are trying to do what we can but we are still experiencing large amounts of vandalism and still seeing incidents of staff being assaulted," he said.
Mr Fox said vandal attacks had caused the recent temporary closure of disabled toilet facilities at the Interchange.
He told councillors that 16 people had been issued with temporary banning orders preventing them from entering the Interchange in recent months as part of a joint initiative with British Transport Police.
He also confirmed talks were being held with Humberside Police and other partners to reduce crime and antisocial behaviour across the city centre, describing a recent pop-up police unit at the Interchange as a great success.
"I believe collective working is the way forward," he added.
Councillors heard efforts to fill three new empty retail units on the main railway concourse were ongoing.
TransPennine is also looking at the option of marketing the old station ticket office as a potential food outlet while a new safe cycle parking hub is due to open at the Interchange in the next few weeks.
