Neve O’Neil was forced to barricade her dormitory room during the mass shooting at Brown University on Saturday.

The daughter of Real Housewives of Sydney star Nicole O’Neil is currently studying at the Ivy League institution located in Providence, Rhode Island.

Now the 19-year-old has broken her silence on the terrifying ordeal.

‘It all happened very quickly, so the first shots were heard at around 4pm at the engineering building,’ Neve told The Daily Telegraph.

She added that upon being made aware of the situation she immediately ran to her dormitory for safety, barricading herself in until it was over.

‘I wasn’t aware of it until my friends called me and asked me where I was and wanted to make sure that I was okay and got to safety. It was definitely a very scary phone call,’ she said.

During the harrowing ordeal, her reality TV star mother shared an update to her social media reassuring followers that her daughter was safe.

‘Neve’s hiding in a dorm with two friends. They have barricaded the door with the bed and are just sitting quietly. The shooter is still at large. It is a tragic situation,’ she wrote.

Nicole, 46, and her husband Adam share two daughters, Neve and Nawal. 

She said what her daughter experienced was every parent’s worst nightmare.

‘When you send your daughters to university to study in America, where the gun laws are very different to the gun laws in Australia, it’s something that’s always in the back of your mind. It’s absolutely heartbreaking,’ Nicole said.

‘But you never think it’s going to happen… and now it’s actually happening.’

Following the shooting, a person of interest is in custody after two people were killed and multiple others were injured.

Police confirmed a male in his 20s was taken into custody at the Hampton Inn in Coventry early Sunday morning.

Providence Police Chief Col. Oscar Perez did not specify if the man is connected to Ivy League and did not state he was a suspect.

The shooter, who is not a Rhode Island resident, fired more than 40 9mm rounds, law enforcement officials said.

Two firearms, a small Glock handgun and a revolver, were found in the hotel room the man was staying in.

One of the guns had a unique characteristic on it and the other was a laser-equipped gun, police said.

The man, who is also not a student at the school, also drove 17 hours from Wisconsin to the state before the attack, law enforcement sources told CNN.

The first reports of shots fired were issued just after 4pm inside a first-floor classroom of the Barus and Holley Engineering Building, where students had gathered to prepare for final exams.

Smiley said the gunman ‘walked right into’ the building because doors were left unlocked for students taking the tests.

Police arrived around 4.22pm and a huge law enforcement response descended on the scene, but by the time officers swept the building the suspect had escaped onto the adjacent Hope Street.

It was during this getaway that investigators captured the chilling surveillance footage showing the suspect walking briskly away from the carnage left behind.

Chaos overwhelmed the campus as students barricaded doors and desperately texted loved ones, with the campus issuing an emergency alert warning anyone in the area to ‘RUN, HIDE, FIGHT’ if they encounter the killer.

Social media was swept with images from terrified students and faculty, showing desks, chairs and possessions pushed up against doors.
