The force relaunched its onslaught on criminal damage, saying it causes agitation and frustration to law-abiding families living in the region.
Assistant Chief Constable Sue Sim said: "We're listening to what our communities are telling us and focusing our efforts on tackling criminal damage.
"This is a crime that can have a huge impact on both individuals and neighbourhoods, leading to increased concern and fear of crime.
"We're taking positive action through more police officers being out on the streets and the work our Neighbourhood Teams are doing alongside partner agencies to curb this offence."
The campaign involved street-level operations, such as the one that snared the four teen taggers.
It is also being backed up by an extensive publicity campaign.
This is the fourth year Northumbria has run a campaign tackling criminal damage.
The graffiti campaign follows on from the Enough is Enough drive at Christmas, which targeted underage drinkers and outlets that fuel the problems by selling booze to under-18s.
