In case of an arrest, the suspect has already been detained in the police station (as you wrote). He/she will have to attend an interview by an on-duty police officer, usually accompanied by a solicitor to protect his/her rights. So the parties involved in the “attendance” will be the suspect and the solicitor, plus the police officer/s who handles the interview.

Also attending would be a police interpreter assigned to support communication if the suspect does not speak English.

This kind of attendance takes place within 24 hours of the arrest since the police has only this much right to detain a suspect before any trial (in Common law UK context).

The suspect might then be released temporarily (or released to return home if there is no case to charge the suspect after the interview depending on the case) and would be asked to return back to the police station when the police needs to conduct further investigation during the temporary release.

This is another type of attendance for the suspect and other related professionals.

Based on the above usual police procedure, I suggest the following:

“到警局应讯” 或 “出席警局约谈”
