Police have appealed for information as they search for a cyclist alleged to have thrown a petrol bomb at a house in south Belfast on Tuesday night.
Alliance MLA Anna Lo condemned the attack, which took place in Fortuna Street at around 11.30pm.
Ms Lo said a man and his 10-year-old autistic daughter were in the house at the time but escaped injury.
She said the incident would have been a “terrifying” one for the victims.
Police said it had been reported that a petrol bomb was thrown at the window of a house and they believe the person responsible may have made off on a bike.
Ms Lo said: “It appears to be simply luck that this attack did not lead to serious injury or even death, but it still would have been petrifying for this man and his daughter.
“Attacks like this create fear and hark back to a time people want to leave behind.”
The South Belfast MLA added: “No-one can even attempt to justify an attack like this. The person behind this is clearly a dangerous individual.
“I would urge anyone with information about this incident to contact the police immediately and help ensure those behind it are apprehended by the authorities.”
On Twitter the Northern Ireland Fire and Rescue Service said two appliances attended a deliberate fire at a house in Fortuna Street but no injuries were reported.
