Two people have been arrested on suspicion of spraying around 120 graffiti tags across Broadstairs.
The arrests were made by officers on patrol in the town after they saw two people acting suspiciously in the Tippledore Lane area.
After approaching the suspects, a 23-year-old man and a 17-year-old boy both from Margate, officers arrested them on suspicion of criminal damage.
They remain in custody as enquiries continue.
