POLICE are looking for witnesses to two arson attacks on a property in Costa Street, South Bank, near Middlesbrough.
The first blaze happened at 1.30am on Tuesday, causing slight damage, but the second fire, at 6.30 the same morning, destroyed the terrace property, which was empty at the time.
Detective Sergeant Dave Turnbull appealed for people with information to get in touch.
He said: "This is a serious matter, which could have had disastrous consequences, if it had spread to the adjoining houses on either side."
Anyone with information is asked to call (01642) 301933.
Four people arrested on Tuesday have been eliminated from police inquiries
