A man allegedly threw a cup of coffee at a $300,000 tapestry at the National Library earlier in the week, in an act of vandalism captured on CCTV.
Police were called to the library on Tuesday morning to view footage allegedly showing the man throwing the coffee onto the Myer Tapestry.
Labratory staff at the library spent several hours trying to remove the stain from the donated tapestry, worth about $300,000. It was donated to the library in December to commemorate the life of long-time library supporter Kenneth Myer.
Police were later contacted by security at nearby Questacon, and were able to locate the man in the area. He was arrested and a number of items were seized that were identified in the CCTV images.
The man was charged with damaging Commonwealth property and possessing a prohibited substance. He is due to face ACT Magistrates Court this morning where police will oppose bail.
