Police hunted floor by floor through a 10-story apartment building Tuesday but found no sign of the man who left seven people dazed and bloody after attacking them with a machete.
They also checked buildings near St. Luke's Church of England school, where the man vaulted over a wall Monday afternoon and randomly hacked at pre-schoolers and teachers."We've searched 80 flats in the 10-story block and there is no trace of him," said Superintendent Richard Green. He said officers also searched garbage chutes, firewells and roofs.
The attacker "was laughing and I didn't really know what was going on," Lisa Potts, a nurse who suffered a broken arm and multiple cuts, told a hospital press officer.
The injured also included a boy aged3, two 4-year-old girls, a teacher, a mother and a playgroup leader.
Teachers reported hearing an argument between a man and a woman outside the school just before the man barged in, disrupting a tea party for the children.
"At the moment there is nothing to suggest he went to the school on purpose," police superintendent Roger Allen said Tuesday.
Police in this city in central England said they were seeking Horrett Irving Campbell, 32. Allen said Campbell had been involved in a violent incident last year and was fined, but he gave no details.
Ahmed Pervez, 3, was recovering Tuesday at Birmingham Children's hospital after surgery to relieve a skull fracture. He also suffered a broken arm and needed stitches on his elbow.
Rhena Chopra, 4, suffered deep lacerations to her face, and Francesca Quintyne, 4, had a fractured jaw and serious injuries to her face and her right ear. Both were in stable condition Tuesday at New Cross Hospital in Wolverhampton.
Potts, 21, suffered two deep cuts on her back, a broken right arm and cuts on her hands and chest.
