Early on Tuesday morning residents of Lennox Head could see smoke rising from a deliberately lit house fire to the north of town.
At about 6.50am emergency services were called to a home on Ross Lane after a 25-year-old woman woke to find a granny flat engulfed in flames.
A man has been charged with intimidation and property offences after the blaze destroyed a home.
The fire was extinguished by the NSW Rural Fire Service and an investigation was launched.
The woman later noticed damage to her vehicle which was parked nearby.
About 9.40am, police attended a separate home on Ross Lane, Lennox Head, where they arrested a 29-year-old man.
He was taken to Ballina Police Station and charged with: common assault, talking/intimidation (x2), use carriage service to threaten to kill, damage property with intent to endanger life, damage property by fire (x2), damage property and use carriage service to menace or harass (x2).
It appears that both parties are known to each other.
The man was refused bail to appear at Ballina Local Court today.
Investigations into the incident are continuing.
