Three men and a teenage boy have been arrested by detectives investigating a serious assault in the Lord Street area of east Belfast yesterday morning.
At 11.55am the PSNI received a report of two men being assaulted by a group of approximately seven males at the junction of Albertbridge Road.
The victims, aged 20 and 21, are being treated in hospital for non-life-threatening injuries.
A 15-year-old boy and three men, aged 20, 23 and 41, are currently being questioned by detectives. A knife was also recovered and has been taken away for forensic examination.
A police spokesman said the motivation for the attack was "not believed to be sectarian" and inquiries were continuing. Last night, Alliance councillor Maire Hendron called for calm in the area.
"I am urging people on all sides to remain calm and to use restraint," she said.
"We cannot have any violence on our streets.
"People need to understand that this is a sensitive time and the smallest incident can do serious damage to community relations.
"If anybody has any information about this incident then I would urge them to contact the police."
Police are appealing for anyone who witnessed the attack to contact detectives at Musgrave PSNI station on 0845 600 8000.
Information can also be provided anonymously to the Crimestoppers charity on 0800 555 111.
