Accused Anzac Day terror plotter faces new charges

Four new charges have been laid against a Melbourne teen accused of planning to kill a police officer in a terror attack on Anzac Day.

Sevdet Besim, 18, from Hallam, has been in custody since April 18 when 200 heavily-armed officers swooped on the city's southeast, arresting five teens and seizing knives and swords.

Besim is accused of planning to run over, then behead, a police officer before going on a violent rampage.

New charges include internet searches of Anzac Day in Melbourne and Dandenong, engaging in communications and creating an electronic memo on his phone - all in preparation for a terrorist attack.

Court documents allege he planned the attack for Anzac Day to "make sure the dogs remember this as well as there fallen heros (sic)".

Police allege he said he was "ready to fight these dogs on there (sic) doorstep" in online communications with a person overseas, according to court documents.

"I'd love to take out some cops," Besim is alleged to have said.

"I was gonna meet with them then take some heads ahaha."

He said he wanted to attack Australia's authority because it would show weakness and put fear into the general population, police allege.

Besim appeared in the Melbourne Magistrates Court on Monday where he was due to face a committal hearing.

The matter was adjourned until January 28.

He has been charged with conspiring to do an act in preparation for or planning a terror act, which carries a maximum sentence of life in prison.
