Mr Karney tweeted on Wednesday morning: 'Extra security measures have caught two males filming themselves urinating on the mural.
'Thanks to GMP they have been arrested.'
I wonder if the average Manchester shopkeeper is wondering if, should he see some yob emptying his bladder against his shop window via CCTV one night, he could expect the Flying Squad to swoop in with such alacrity?
The clue is in 'mural' - of dead American criminal George Floyd.
The latest incident comes two days after the painting was defaced with racist graffiti for a second time.
On Sunday night, the memorial was targeted after a large 'N' was sprayed over it.
The mural was also defaced with vile graffiti last summer when a masked vandal sprayed 'n****r' over Mr Floyd's face.
Clearly, this 'tribute' is doing one good job - becoming a magnet for vandals and keeping them away from other areas!
Councillor Jon-Connor Lyons said the artwork has since been covered up 'to prevent further graffiti or cause any emotional damage to our communities.'
Anyone caused 'emotional harm' by damage to this mawkish, out-of-place so-called 'artwork' needs psychiatric help...
A spokesman for GMP said: 'Officers received a report around 1am on Wednesday 17 February 2021 of two males urinating against a George Floyd mural in Stevenson Square, Manchester.
'Officers attended and two men, both aged 22, were arrested on suspicion of racially aggravated criminal damage. They remain in custody for questioning.'
Unless they were aliens with acid urine, I think any competent solicitor will be able to prove no 'damage' has occurred that wouldn't be erased with a mop.
