Allan Fenton is alleged to have tattooed the girls during the summer holidays at his home in Dundee's Gotterstone Drive. The case comes just weeks after a Scottish police force launched a crackdown on illegal "tattoo parties". Fenton faces two charges of carrying out a tattooing business without a licence and two of tattooing girls under the age of 18.
One of his subjects is said to have turned 16 three days before she was tattooed, while the other was just 14. The offences are alleged to have happened on July 1 and between July 21 and 23.
Fenton did not appear at Dundee Sheriff Court to face the charges. His lawyer, Michael Short, entered not guilty pleas on his behalf. Fiscal depute Chris McIntosh asked for a trial date to be set as soon as possible because child witnesses are involved.
Sheriff Alistair Duff ordered Fenton to attend court for a pre-trial hearing on November 23 before standing trial on December 15. In October, Central Scotland Police launched a crackdown on unlicensed tattoo artists after reports that a number of children under the age of 18 were given illegal inkings at a house party in the Falkirk area.
Tattoo parties - where an artist attends a gathering and gives tattoos to whoever wants them - are on the rise, police said. But the artists are often unlicensed and work on under-18s, who are banned from obtaining tattoos.
The force said it had been made aware of another incident in which a unlicensed tattooist worked on a child aged just nine. There are also problems with the lack of proper health and safety procedures at the parties.
Public health specialist Dr Henry Prempeh said: "A tattoo can lead to serious infection if it is not done by a trained tattoo artist. "The risks increase significantly if tattooing is carried out in premises that are not fit for purpose and regularly maintained."
