Nigel Brock, who lives at William White Place, says he has spent the last 11 years trying to get the police and housing bosses to crack down on yobs trespassing onto the property and causing trouble.

The 70-year-old, who worked in the construction industry, describes witnessing "groups of five or 10 people" loiter and drink there.

He said: "They sit outside in groups and they are very noisy and agitated and violent and urinate everywhere."

Mr Brock has been gathering evidence of the intimidating behaviour for several years and reporting it to the authorities but the problem has continued to persist.

He said: "It's really bad. I've contacted the police, the council and my landlord but it feels like no one is taking responsibility."

Mr Brock has become so frustrated with the ongoing issues that he now confronts groups of yobs in a bid to move them on.

He said: "In the last six months I've asking them to move on myself but I've been met with verbal abuse and aggression."

Mr Brock also claims there were past instances of people congregating under a bin shed outside the block of 60 flats and leave drug paraphernalia - like spoons and tinfoil - until locked fencing was installed around it.

He added: "This is a lovely community and there are children here but this is not a safe environment for them."

Who are the culprits?

William White Place is owned by Orbit Group and neighbours the Bishopbridge Hostel, which is run by St Martins Trust.

Mr Brock believes most of the troublemakers come from the hostel and says he has seen them leave the hostel towards William White Place.

But Jan Sheldon, CEO for the trust, says after investigations they often find incidents of anti-social behaviour do not involve their tenants.

Ms Sheldon said: "St Martins takes any complaint we receive seriously and we always investigate incidents thoroughly and promptly.

"Quite often we find that the people involved in the incidents bought to our attention do not reside in our properties. 

"If we have the evidence to confirm that any person using our services has exhibited anti-social behaviour, we always take appropriate action. We work closely with the police and Norwich City Council to address shared concerns."

On Monday night, police were called to the hostel on Gas Hill shortly before 6pm.

They arrested a man in his 40s on suspicion of assault and took him to Wymondham police station for questioning where he remains. No one was injured.

A spokesman for Norfolk police said: "We are aware of reports of anti-social behaviour in William White Place. Officers continue to carry out routine patrols in the area, hold drop-in sessions and work closely with our partners to address this type of behaviour.

"We always encourage incidents of anti-social behaviour to be reported to us via 101 or through the Norfolk Police website."

A spokesman on behalf of Orbit Group, which runs the block of flats, said: "We are disappointed to hear of antisocial behaviour in the neighbouring area and understand the negative impact that these issues have on local residents.

"We encourage all of our customers to continue to report any concerns they are aware of to the police and local authority."
