TELUK INTAN Polls close at 5pm with a relatively low turnout of 67.4 percent votes and 40,236 votes.
This is below the DAP target of 70 percent, which it had hoped can push its newbie candidate Dyana Sofya Mohd Daud ahead of against BN veteran Mah Siew Keong.
In 2013, turnout at Teluk Intan was a record 80.4 percent. DAP had then won with a majority of 7,313 or 15 percent of total votes.

8.24pm: QUICK ANALYSIS
There appears to be a slight swing of Chinese voters back to BN.
Significantly, Batu 12, a previous DAP stronghold was won by BN. DAP won by 68.5 percent of votes last year.
This time, BN won by 51.53 percent. BN won all three voting streams at the Chinese new village.
Batu 12 is located on the outskirts of Teluk Intan, but stream data shows BN also gaining in town areas.
BN raises its takings in Chinese-majority polling stations at Pasir Bedemar, a town area won by the DAP in 2013.
8.20pm: Gerakan operation centre - Victorious candidate Mah Siew Keong speaks to his supporters after a short meeting with his campaign team.
He urges for everyone to stay calm should there is any dispute of the results.
"Have you eaten? Where is the Kentucky (Fried Chicken)?
"The unofficial results are out but our opponent is now challenging the result.
"If the Election Commission does a recount in the next few hours we can be patient, unlike that other party which is so impatient that they wrote everything on the internet that they had won.
"We respect the law and we are patient. Have you eaten? Let's eat together," he says to applause from supporters.
8.09pm: DAP Canning state assemblyperson Wong Kah Woh asks supporters to be calm and says the party will work harder at the next general election.
Since the unofficial result is very close, the party will look at the possibility of a recount, he says.
"There is over 500 of majority votes, and since the majority is marginal, we are looking at the possibility to recount," he said through a megaphone.
"The team is now considering if we are going to recount."
This despite the fact that election regulations do not allow recounts after ballot boxes are sealed.
A recount can only be done at the counting centres, before ballot boxes are sealed and polling agents sign off on the tally at voting stream levels.
A recount can only be done if the difference between the votes by each candidate received, at the stream level, is less than four percent.
7.55pm: BN candidate Mah Siew Keong arrives at the party's operation centre all smiles and shakes hands with supporters.
His supporters carry him while chanting: "Mah Siew Keong!"

DAP supremo Lim Kit Siang says in a tweet message that the voters turnout is low.
“66.5% - quite a poor disappointing voter turnout in the Teluk Intan by-election as compared to 80.4% last May in the 13GE. Can be a toss-up!”
5.50pm: The relatively low turnout of 66.5 percent is giving BN early confidence that it could wrest Teluk Intan from the DAP.
"Personally, I feel BN has won!" former Perak senior executive councillor Hamidah Osman tweets.
