There were angry scenes at the Holy Cross standoff today as tensions spilled over on the disputed North Belfast school run.
As political efforts to resolve the crisis continued, one woman loyalist protester was arrested during a confrontation between picketers and a catholic parent walking her child to class.
Ms Philomena Flood, a member of the Right to Education Group, claimed her seven-year-old daughter Eirinn was taunted while passing residents in the Protestant Glenbryn estate.
As she returned Ms Flood stopped at police lines and pointed towards those she said were behind the abuse.
Furious residents began shouting at her, with one woman immediately arrested by police and bundled into a jeep.
The angry exchange came as increasing numbers of children used the school buses specially laid on to take them to Holy Cross.
With the rain driving down, about 25 pupils and their parents went up the disputed Ardoyne Road on three bus runs.
