Renewed appeals are being made following an arson attack in Crawley.
A piece of cloth was pushed through the letterbox of a ground floor flat in Titmus Drive last month. It was then set alight using petrol.
A black jerry can was left at the scene of the attack the early hours of September 23rd.
The occupants, two adults and a five-month-old baby, escaped unharmed.
Three men were seen getting out of a small black car in Tilgate Parade shortly before the alarm was raised. It is believed they may be important witnesses to the incident.
