The incident was reported to police around 1.18am on Wednesday morning. Police at first described it as a “detonation”, but later said there was no evidence that there had been any explosion, and that an object had been thrown through a window.
Several people were in the house at the time and all were taken to hospital by ambulance, but were able to leave the hospital later on Wednesday.
“It didn't seem to be a case of life-threatening injuries,” police officer Mikael Ehne told the TT newswire.
The windows of the building were also damaged and the area was cordoned off while a technical investigation was underway.
“It's hard to say how extensive the damage is. We don't want to go in and touch anything until the technicians have done their investigation,” said Ehne.
Police have opened an investigation into attempted murder but no individual is currently suspected.
“It is a serious incident, absolutely,” Ehne commented. “There is information we have received and witness statements taken at the scene that mean we have reason to believe it could be a murder attempt.”
He also said that he didn't think other people in the area had any reason to be concerned for their own safety.
