The 24, 27, 37 and 200 Lothian services have been redirected due to antisocial behaviour at the Pennywell Road area.
According to the official Lothian Buses Twitter account, the same services were affected for the same reason six days ago.
From 5pm on Sunday, the 24 and 200 services have been redirected via Ferry Road. This is to avoid Pennywell Road and West Granton Road.
The 37 and 27 are also unable to serve Pennywell Road along with Muirhouse Parkway. Both services will instead follow Ferry Road and Silverknowes Road in both directions.
All four services will be diverted until further notice.
There have been several accounts of antisocial behaviour which has involved and targeted Lothian buses. Some of the bus drivers have been injured because of these attacks.
As of last Wednesday, chief inspector Sarah Taylor said officers have now charged 30 people in relation to such incidents.
