Four West Brom players have apologised for an incident during the club's mid-winter training trip to Spain for which they are being investigated by police.
Jonny Evans, Gareth Barry, Jake Livermore and Boaz Myhill have been accused of stealing a taxi early Thursday morning, and they took responsibility after neither the club nor police named them.
"We felt it important we identify ourselves out of respect for teammates who otherwise could be implicated by association," the quartet said in a statement.
Catalonia's regional police told The Associated Press that the players were taken before a judge after being accused by a taxi driver, who said he was outside the vehicle at the time it was stolen. Police said there was no violence involved.
The Baggies announced on Friday that they have opened an investigation into the matter but did not confirm any further details.
The club say the quartet will be "subject to the full rigours of our internal disciplinary procedures," and that they will make no further comment until their investigation is completed.
West Brom were in Barcelona on a three-day trip while preparing for Saturday's FA Cup fifth-round game against Southampton.
Pardew said at a news conference on Friday: "It wasn't what we wanted. We have gone there to try to get ourselves up and ready for this run-in, and this is obviously not ideal.
"They break a curfew, and that is unacceptable, and I feel a bit let down by that. There was a curfew on that evening and it was broken, and that is really all I'm going to comment really.
"As much as you want information and stuff, I think the club is clear it wants to investigate it properly, and I think that's right, and we just want to concentrate on the game now, because it is a very important one for West Brom tomorrow.
"We have 11 games left and we are in the last 16 of the FA Cup, and our fans will want to see us put in a performance tomorrow."
Asked if he would understand if the fans felt let down, Pardew said: "Absolutely, and we have to respond with a performance tomorrow."
West Brom -- who are bottom of the Premier League and seven points adrift of safety -- earlier this week sacked chairman John Williams and chief executive Martin Goodman, with Mark Jenkins returning as chief executive.
Regarding that, Pardew said on Friday: "Of course, they are good people and I was disappointed if I'm honest.
"But the club made that call and now we have a new CEO in, I've met him and we are going to move forward hopefully, together.
"I think we need to kind of make sure everything is geared to the 11 games we have left in the league and this little cup run, which could turn into a big cup run. It is just about getting the best we can out of our group."
Asked if he was confident his position was safe, Pardew -- appointed in November -- said: "I think [with] all these situations, you can't be certain of your job, you just have to try to do your job, and that is what I will do.
"I am an experienced manager and I'll try to use my experience to get us out of this situation. I'm confident that we are going to put performances [together] that give us the chance to do that."
Pardew also said on-loan striker Daniel Sturridge was set to miss the next two games due to his hamstring injury.
