Two people were sent to hospital after an overnight fight involving machetes in a Winnipeg alley.

One of the victims is in critical condition, police said.

The fight broke out between two groups of people at about 1 a.m. Friday in the 200 block of Pritchard Avenue, in the city's North End.

Some of the weapons were found at the scene by emergency crews.

Four people — two of whom had to be treated for injuries — are in custody.

Investigators are still interviewing witnesses to determine what charges will be laid.
