A second man has been charged in relation to an alleged planned terrorist attack on an Anzac Day ceremony in Melbourne.

On Saturday, Victoria Police and the Australian Federal Police arrested five men in pre-dawn raids in Melbourne’s south-east, as part of an ongoing investigation into a suspected terror plot aimed at Anzac events in Victoria.

Victoria Police confirmed on Monday that an 18-year-old Narre Warren man has been charged with weapons offences.

He faced the Melbourne Magistrate’s Court on Saturday and was remanded to re-appear at court on Friday, April 24.

Police said an 18-year-old Hampton Park man is being held on a Preventative Detention Order. He remains in custody and has not been charged.

They said two other Narre Warren men, aged 18 and 19, have been released pending further enquiries.

On Monday, Victorian Premier Daniel Andrews said he would not be deterred from Anzac Day commemorations where unprecedented levels of security will be in place after the terror threat.

Mr Andrews will attend the dawn service on Saturday with his wife and daughters and encourages all Victorians to do the same around the state.

“The police did us proud over the weekend and they will again on Anzac Day,” Mr Andrews said.

Victoria Police Acting Chief Commissioner Tim Cartwright said several hundred police would patrol Anzac Day commemorations with a noticeably increased security presence.

“We will see several hundred police present, we will see physical security arrangements in place which we won’t have seen before,” he said.

“There are other arrangements which will not be visible.”

He said they were not restricting the police presence just to the Anzac Day dawn service, or just to Melbourne events.

“We are looking right through the week in terms of Anzac-related events and reviewing security at each of those venues and each of those events.”

Police will leave “no stone unturned” when it comes to Anzac Day security, he said, but they understood some Victorians would still be apprehensive.

‘More help needed’: Muslim community

A Muslim leader called for more help on Monday as police continued investigating the alleged terror plot in Melbourne.

Victoria’s Islamic Council secretary Kuranda Seyit said the Muslim community was struggling against the “slick campaign” being run by ISIL to encourage extreme violence.

“Muslim leaders need to be given the tools to get through to these people and we don’t presently have a group that can relate to these people,” he told Macquarie Radio.

Mr Cartwright said complaints from two of the families about the conduct of police during the raids had been received, and the one formal complaint about misconduct would be investigated.

He said he was not surprised there were minor injuries in a high risk operation into threats of violence linked to Anzac Day events in Victoria.

“My understanding was that OC spray was used on at least one of the men and there was resistance there,” he said.

“There would routinely be forced used to some degree. We seek to immobilise the person to make sure they don’t have access to weapons.”

However, police were concerned about allegations of excessive force and derogatory language, and officers would look into them, he said.

Self-styled Islamic preacher, Junaid Thorne, who has links to ISIL fighters, supported the five young men on Monday, describing the raids as the “usual nonsense”.

Mr Thorne has been a regular speaker at the controversial Al-Furqan Centre in Springvale in Melbourne, where the five men also attended.
