Sullivan is determined to find the serial burglar who has targeted around 50 other properties in the area since Christmas 2016, targeting mostly watches and jewellery.
The West Ham chief has offered a substantial offer to anyone who might have information relating to the thief who has been dubbed the ‘Essex Spiderman’ to come forward and reveal his identity.
Sullivan’s hi-tech security systems are believed to have scared off the burglar on this occasion and his attempt was unsuccessful.
But the Sullivan family have clearly been affected by the break-in and want to ensure the culprit is made to pay for his actions.
Sullivan said: “To have someone break into your home is an awful experience, and I hope this reward will help bring the individual responsible to justice and prevent others going through the same ordeal.”
Sullivan’s £7.5million mansion in Theydon Bois, Essex, was featured on Channel 5 TV show ‘How the other Half Lives’ last year and has a huge indoor swimming pool, jacuzzi, bowling alley and full-size snooker table.
This is not the first time the Hammers supremo has handed out a gesture to the public.
Sullivan acted quickly to support the people who had been affected by the Manchester terror attack when he got in touch with the homeless man who helped victims in the aftermath of the tragic events at the Manchester Arena.
Stephen Jones was sleeping rough close to the city centre when the explosion which killed 22 and injured more than 60 people took place.
After realising what had happened he rushed to the aid of those hurt in the blast.
Upon hearing this account, Hammers chief Sullivan pledged to offer shelter and money to the 35-year-old.
