Two teenagers have been charged after allegedly sending a Brisbane Woolworths store into lockdown.

The girls, aged 14 and 15, allegedly caused chaos at the Woolworths Keperra store at about 3pm yesterday afternoon.

Witnesses claim a manager was allegedly hit with a bottle and an innocent shopper was also caught up in the scuffle.

Both teens had their matters heard in a children's court today. 

The 15-year-old is set to face court again on Wednesday.
