Giant blue heart tributes to the NHS have been painted on roads near Gravesend by a mystery crew of workers in the dead of night.
The quality of the markings suggested to many that council workers were behind them but Gravesham, Kent and Meopham councils have denied responsibility.
Four have appeared on the A227 – on the approach to Meopham Station, by Bartellas, outside Camer Parade and outside of Meopham School. Two more have been found on Sole Street and another in Cobham.
Residents report seeing a white van with flashing lights and a group of men working on the markings at around 3am on the week of April 20.
Meopham Parish Council is searching for the mystery artists.
A spokesperson said: "It is a lovely gesture and it would be nice to know who did this."
Several local NHS workers wanted to show their appreciation. Diane Thomas said: "Spotting this on my way home after a shift really lifted my day. Whom ever it was, thank you."
Many in Meopham are intrigued who painted and paid for them - enjoying the thrill of a puzzle during an otherwise dull lockdown.
Ann Hoysted discussed the evidence on Meopham News & Views. She said: "They are so lovely and it's professionally marked. However maybe the person wants to remain a mystery and if they do, we should respect their wishes.
"I'd imagine if Gravesend have no markings, this may be because traffic is quieter here or it could be someone local. We may never know. Such a mystery."
The search goes on.
