Tech giant Apple say they have apologised to six black students after they were told they could not come into a store in Melbourne because staff thought they might steal something.

On Tuesday afternoon, year 10 students from Maribyrnong College in Melbourne's west visited an Apple store at the nearby Highpoint Shopping Centre in their uniforms.

The students accused Apple of "racial profiling" after one of the students said he and his friends left the store, but later returned and a security guard told them they could not re-enter.

One of the students filmed the exchange on their phone.

"These guys [the security guards] are just a bit worried about your presence in our store," an Apple staff member can be heard saying in the video.

"They're just worried you might steal something."

A member of the group then replied: "Why would we steal something?"

Apple told triple j's Hack in a statement that they have apologised to the students.

"We've looked into the details of the situation and we apologise to the customers involved," Apple said.

"We will continue to do everything in our power to ensure all our customers are treated the way they should be.

"Inclusion and diversity are among Apple's core values.

"We believe in equality for everyone, regardless of race, age, gender, gender identity, ethnicity, religion or sexual orientation.

"That applies throughout our company, around the world with no exceptions."

Angry with how they were treated, the students uploaded the video to Facebook.

Student Maboir Ater said it was not the first time he had experienced "racial profiling".

"When we walk into a store with a group of minimum three people, the security watches us — they follow us and that just makes us feel like we're not welcome in the store," he said.

"They judge us before we can show our character.

"It's because we're teenage boys, but also because we're black teenagers.

"They see us and think of all the stereotypes."
