Four young men have been questioned over a racist attack on a educational facility opened in memory of murdered teenager Stephen Lawrence.
The facility was opened earlier this month
Six windows were smashed, causing £120,000 worth of damage, a week after the centre officially opened in Deptford, south London, on 14 February.
The centre works to inspire youngsters to pursue careers in architecture.
Police said the four, aged 19, 20 and two aged 17, have been bailed after their arrests earlier this week.
A spokeswoman for the family said the attack was the fourth time it had been targeted since last October.
Stephen, 18, was murdered at a bus-stop in Eltham, south-east London, in 1993.
