Multiple people were reporting on Twitter an incident that appeared to be an active shooting at the Shops at Montebello, as panicked shoppers ran for cover or sheltered inside stores.
Montebello police, however, tell Eyewitness News there was no shooting at the mall.
A police spokesman did not immediately have full details on the incident, but said an individual is in custody.
The spokesman added that there was no weapon involved in the incident and no injuries reported.
A smash-and-grab robbery at the same mall in 2019 set off a similar panic among shoppers who heard the sound of smashing glass and took it for gunfire.
