Ensuring people feel safe near their homes has been the priority after police stepped up patrols after reports of public drug dealing and taking.
Officers received a tip-off from someone living in the area about the drug activity taking place in an alley between Knowland Grove and Jamieson Place in the Marlpit estate, near Earlham.
Following reports, the area's beat manager PC Shaun Collingsworth carried out patrols in the area and officers will carry out further patrols and enquiries.
The street has become something of a city crime hotspot with a number of reports of flytipping and a man reported to be following women and young people last year.
The area's Labour county councillor, Maxine Webb, was impressed with how quickly police had responded to the drug issues.

She said: "They've reacted very quickly, the beat manager is brilliant there and really works with the community, that's why it's happened so soon.
"He gets information like this from his crime surgeries and these patrols are absolutely needed.
"It is an area that has incidents every now and then, but the location changes every so often.
"If it's in Knowland Grove at the moment then it's great to have that presence.

"Hopefully they can quickly get on top of it and take action against those who are responsible.
"Then hopefully people can start to feel safe again."
It comes as police crackdown takes place in a number of problem areas in the city, with officers monitoring a Lakenham homeless shelter after a man's drug "nightmare", the Castle Gardens and outside McDonald's in Haymarket.
City folk have reported a number of issues arising from drug activity since the turn of the year with those in NR3 saying their parks have been plagued with used needles.
A raid was also made at a home in Lower Clarence Road on Thursday, where crack cocaine and heroin were siezed.
