A New Jersey family say they've been forced out of their luxury home by a stalker who identifies himself as the home's 'Watcher' in letters threatening their children's safety.

Maria and Derek Broaddus began receiving letters last month - just days after closing on the $1.3million dream home in the idyllic community of Westfield.

'Why are you here? I will find out,' the letter read.

'My grandfather watched the house in the 1920s and my father watched in the 1960s. It is now my time. Do you need to fill the house with the young blood I requested?'

The letter is signed 'The Watcher'.

Under observation: The house in Westfield, New Jersey, that is being targeted by a 'Watcher' who claims his family has been stalking the property since the 1920s

Who is the Watcher? House owners Derek and Maria Broaddus, pictured with their three chldren, bought the property recently but have been too scared to move in after receiving menacing letters

It suggests 'The Watcher' has been monitoring the Broaddus family - which reports have not named - because he makes reference to their three young children.

'Once I know their names I will call to them and draw them to me,' the stalker writes in the first letter dated June 5.

IS 'THE WATCHER' OBSESSED WITH BEAUTIFUL OLD HOUSE? In letters by 'The Watcher', he writes: 'You have changed it and made it so fancy...it cries for the past and what used to be in the time when I roamed its halls...when I ran from room to room imagining the life with the rich occupants there...and now I watch and wait for the day when the young blood will be mine again... (The house) is turning on me it is coming after me...I am in charge of it...Let the young blood play again like I once did...Stop changing it and let it alone' Advertisement

'I asked the (prior owners) to bring me young blood. And now I watch and wait for the day when they (sp) young blood will be mine again.'

Subsequent letters, reports NJ.com, have been even more threatening toward the couple's children.

'Have they found what is in the walls yet? In time they will. I am pleased to know your names and the names now of the young blood you have brought to me,' one letter reads.

'Will the young bloods play in the basement. Who has the rooms facing the street? I'll know as soon as you move in. It will help me to know who is in which bedroom then I can plan better.

'All the windows and door in (the house) allow me to watch you and track you as you move through the house.

'I am in charge of (the house).' The family, who have been too fearful to move into the home, are now suing the previous owners - John and Andrea Woods - on claims they knew about The Watcher and failed to disclose the information.

Deception? The dream home was bought for $1.3million but the new owners are suing the previous owners for allegedly withholding the fact that it is being stalked

Intimidated: The Broaddus family are scared to step through it in case they are being watched by stalker

Investigating: Mayor Andrew Skibitsky said at a town hall meeting Tuesday night: 'Our police have conducted an exhaustive investigation into the threatening letters. Our police went the extra measure and left no stone unturned.'

HOME COMES WITH 'STUNNING MASTER SUITE AND BUILT-IN WINDOW SEATS'...BUT THERE'S NO MENTION OF 'STALKER' IN SALES PITCH A real estate listing for the $1.3million home in a sought-after, upper-crust neighborhood mentions several selling points - but doesn't say the house comes with its own stalker too. The grand turn-of-the century home is on a stately street close to public transportation and an award-winning downtown. Period features include high ceilings, coffered ceilings, elegant foyers, built-in window seats and fireplaces, according to Zillow. The stunning master suite boasts a custom dressing room/closet and renovated bath. There are two porches - a covered but open front porch and an enclosed side sun-porch. An open staircase leads to the third floor, which has a sitting area, two bedrooms and renovated bath with skylight. A playroom is located in the basement. The listing boasts: 'Enjoy top-ranked Westfield schools and community!' Advertisement

The lawsuit reads, in part: 'This action arises out of Defendants' fraudulent, avaricious, intentional and negligent concealment and misrepresentation of material facts regarding the single family dream home Plaintiffs were purchasing located at 657 Boulevard, Westfield, New Jersey (hereafter "the home"), which defendants, John Woods and Andrea Woods sold to the Plaintiffs on or about June 2, 2014 for the sum of One Million Three Hundred Fifty-Five Thousand Six Hundred Fifty-Seven ($1,355,657.00) Dollars, despite knowing the potential harm that could foreseeably befall the Plaintiffs and their three (3) minor children.'

Naming the previous owners, Chicago Title Insurance Company and even 'The Watcher,' the frightened family say in court filings that the previous owners received a letter from The Watcher just days before the closing.

Meanwhile, local authorities and even the town's mayor have gotten involved. Mayor Andrew Skibitsky said at a town hall meeting Tuesday night: 'Our police have conducted an exhaustive investigation into the threatening letters. Our police went the extra measure and left no stone unturned.'
