A racially motivated incident took place on Friday night in Daventry.
It happened at the Shahi Lounge in the High Street and saw three suspects arrested all of whom remain in custody.
Sergeant Sam Dobbs from Daventry Safer Community Team said: “Arrests have been made in relation to this incident, which we believe to be racially motivated. No-one was stabbed as a result of this incident which is subject to a robust investigation.
“Incidents of this nature in Daventry are extremely rare and there is no suggestion that businesses run by Asians in the town are now under threat because of what happened on Friday night.
“We will not tolerate anti-social behaviour or racism in Daventry and if anyone has any concerns about any such issues in the town, and haven’t spoken to us already, then please ring the Safer Community Team at Daventry on 101.”
The premises is due to be open tonight (Monday).
Two people appeared in court earlier today in connection with the incident.
