Three Roman gladiators caused a stir at council offices as they protested against plans for bus lane routes along a busy Cardiff road.

Proposals to build new cycle and bus lanes on the A469 in the north of the city has angered local people who fear more congestion.
They believe the road was first built by the Romans in AD50 and donned fancy dress to highlight their campaign.
The council will discuss the proposals at a meeting on 8 April.
The three activists, Andrew Williams, Martin Haines and Amjad Mohsin, met with Cardiff Council leader Russell Goodway after the cabinet meeting.
"He gave us a few minutes of his time but didn't really commit himself one way or the other," said Andrew Williams from the A469 Save Our Streets Campaign.
The idea to dress up to make their point was no April Fool's joke, as the campaign has attracted serious support.
Mr Williams said: "The strength of feeling about these proposals is huge, we have collected a petition with thousands of names of people who are against it.
"It just seems that they have not thought this whole thing out properly and have not done proper consultation.
"We have had a lot of support from the local councillors living in the area and people just don't want these proposals to happen.
"You have only got to look at the posters that are in the windows of the houses either side of Caerphilly Road to realise how people feel," he added.
This protest is the latest in a long line of events staged by the group including marches and meetings.
"This is about trying to highlight the issue," said Mr Williams.
"We are trying to show how much people do not want these changes to be brought in."
The group have been campaigning for the £2m scheme to be withdrawn because they fear that the congestion on the roads will become worse.
But the scheme has had the support of the cycle users group Cardiff Cycle and has been drawn up as part of the council's aims to cut bus journey times and reduce city centre traffic.
A spokeswoman for Cardiff Council said that they would not be commenting about the scheme until it is discussed at the cabinet meeting next Thursday but said that full consultation had taken place.
