A gang responsible for a spate of assaults and incidents of racial abuse targeting black people is being sought in Tilbury, Essex.
Three violent attacks have been reported this month, and Essex Police have increased patrols in the area.
A 26-year-old student was punched and abused in a park near Brenner Road.
A 41-year-old IT worker suffered the same treatment in Adelaide Road, and a man was assaulted by a gang of youths near the railway station.
Police are looking for the gang members and have appealed for local people to provide them with names and addresses of suspects.
They are also working closely with shops and businesses in the area, and have had meetings with leaders of the black community to assure them of their efforts.
Insp Mark Wheeler said: "We've seen an annual rise in race hatred over the past few years. There is a need for tolerance and understanding to feel the benefits of living in a multi-racial society.
"These people in gangs are cowards and I urge local people to provide us with names and addresses so we can track them down.
"All the attacks have been against Afro-Caribbean people and we have increased patrol to both assure them that security is being increased and to gather intelligence about those responsible for the attacks."
