(CNN) Police have arrested a 20-year-old man in connection with the killing of exchange student Aiia Maasarwe in Melbourne, Australia, authorities said in a news release Friday.

The body of Maasarwe, a Palestinian from a predominantly Arab city in Israel, was found early Wednesday in Bundoora, a suburb about 16 kilometers (10 miles) from Melbourne's center.

The suspect was arrested by police in in Greensborough, another Melbourne suburb less than 10 kilometers (6.2 miles) from Bundoora, police said.

Aiia Maasarwe is seen at Caesarea beach in Israel on January 23, 2017, in this photo supplied by her cousin Manar.

Detective Inspector Andrew Stamper said Maasarwe, an exchange student at nearby La Trobe University, had been the victim of an "absolutely horrendous, horrific attack."

Police found a hat and a shirt about 100 meters (328 ft) from the crime scene, which Stamper said were believed to be left behind by the person responsible for Maasarwe's death and were "key to solving this crime."
